Buy the parts for the PCB build¶
Two complete fixtures · LIGHT v0.2 / cbb8d9fc · reviewed 13 September 2026
Check a required line when its full quantity for both fixtures is covered by an order, usable stock you will have in Canada, or an equivalent included part. If you choose an alternative below, also check the required line it replaces; that line will then leave the remaining-shopping list. Your checks save in this browser, independently of the earlier bench checklist. They do not sync between your phone and computer.
Selection notes matter: “Specified” identifies the required part; it does not certify supplier stock or delivery. Rows saying “Select” or “Confirm” still need that decision before purchase. DigiKey Canada product links were checked on 13 September 2026 where an exact match or clearly labelled candidate was found. Prices, stock and delivery dates can change; verify them in the cart. A Canadian storefront does not mean the parts ship from a Canadian warehouse. Printed gimbal structures and diffuser supports are excluded.
Order from fewer suppliers: DigiKey links below cover the cable-side connectors, shorter PA/PH leads, Carclo optic, mounting tapes and selected assembly supplies. Keep the specialist sources for the manufactured PCBs, VALENT X tape, motors, custom spotlight star/housing, diffuser and aluminum tube. PSU/input hardware, moving-wire specification and dimension-dependent fasteners still need selection. Do not add the already-fitted main-PCB components to your order.
Manufactured boards0 / 4 checked
| Product / SKU · mark when ordered | For two fixtures | Selection | Used for / purchase detail |
|---|---|---|---|
| Board and factory BOM | 2 complete assemblies | Specified | Both faces assembled; 241 fitted parts per board, including C504 and all board-mounted connectors. A five-board fabrication order leaves three bare spares; those are not additional complete fixtures. |
| Flex requirements | 2 | Specified | One per fixture. Factory reinforcement and connector mating thickness belong in the PCB order. Its tail plugs directly into J2; no separate FFC cable. |
| Flex requirements | 2 | Specified | One per fixture. Bare passive flex; do not order assembly of LEDs or generic connectors onto it. |
| Flex requirements | 2 | Specified | One per fixture, with the seven specified back PI supports. User wiring solders to its stations. This is a static flex, not the moving hinge. |

|---|---|---|---|
| Lorenz · 416AT size catalogueMetal Supermarkets Victoria · cut-length quote | 4 cut bodies · 2 fitted + 2 spares | Supplier quote / fit check | Current requested size: actual 4.000″ OD, 0.065″ wall, nominal 3.870″ ID and 3.500″ finished length. Request square, deburred ends and a smooth uncoated exterior. Confirm alloy, tolerances and availability with the supplier. Two extra bodies are prototype spares; this is still a two-fixture BOM. Thermal performance needs the assembled prototype check. |
| Manufacturer | 1 × 16.4′ spool | Confirm cut layout | For two fixtures: 48 × 2.46″ radial segments plus two provisional 9.84″ Zone 7 segments = 11.48′ before waste. One spool leaves about 4.92′. Zone 7 length is not finalized; 9.84″ does not encircle a 4″ OD tube. |
| Motor specifications | 4 motors | Confirm order suffix | Two axes per fixture. Match the exact variant on your existing motors; confirm whether four matching motor cables are included. Subtract usable inventory you will have in Canada. |
| Configure star | 2 | Confirm configuration | Match the bench’s warm-white XP-E2, cool-white XP-E2 and PC Amber. Ask for individually addressable construction with six isolated ± pads and no common connection. Confirm exact CCT/bins and availability; SJX-1 alone is a board marking, not a complete ordering code. |
| Housing | 2 | Confirm fit / thermal | Existing housing identified in Doc 3b, for a 20 mm 3-up star and optic. Manufacturer describes ~3 W passive use and recommends ~350 mA for a 3-up. Confirm clearance and temperatures with the selected emitters and enclosure. |
| DigiKey Canada · 1066-1054-NDCarclo fit data | 2 | Confirm emitter fit | One primary optic per spotlight; verify with the configured star and housing. 10508 / 10509 are optional beam experiments rather than required extra optics. |
| Installation instructions | 1 small package | Select SKU | Thermal interface under each star and on the housing threads as required by the housing instructions. Confirm material compatibility and mounting method; do not count an unrelated bench heatsink as an additional fixture part. |
| Manufacturer SKU | 1 × 15-sheet pad | Confirm sheet layout | 11″ × 14″ translucent sheets, your preferred stiff diffuser. The current maker SKU uses YPT; the earlier Amazon listing used L21-YUP153WH1114. Confirm diffuser diameter, seam overlap, height and layers before cutting. |
| DigiKey · 4611-0.5-5 roll3M thickness data | 1 roll · ½″ × 5 yd | Trim width to band | 12.7 mm × 4.6 m roll; about 1.30 m is fitted under the four upper/lower flex band bodies. Cut to the 6.4 mm band width and leave solder/access regions clear. Not automatically under the LED strips. Preserve the specified nominal 1.1 mm adhesive stack; verify alignment against the fit drawing. |
| DigiKey · 467MP-0.5-5 roll3M product | 1 roll · ½″ × 5 yd | Confirm cut template | 12.7 mm × 4.6 m roll, wide enough to cut the 9.2 mm static gimbal-flex mounting template for two fixtures. User-applied mounting adhesive, not the factory PI-support adhesive. Keep soldering access, joints and cut regions clear according to the mounting template. |
Cable-side plugs and wire0 / 16 checked
| Product / SKU · mark when ordered | For two fixtures | Selection | Used for / purchase detail |
|---|---|---|---|
| DigiKey Canada · 455-1488-ND | 4 housings | Specified | Main PCB J12 pan and J13 tilt: four housings total. Pin order is power, GND, CAN H, CAN L. PA and PH both have 2 mm pitch but do not mate. |
| DigiKey · 2″ APAPA22K51DigiKey · 4″ APAPA22K102DigiKey · 6″ APAPA22K152 | 16 pigtails; choose cut plan | Confirm short routed length | Short replacement for the former 12″ lead: same SPHD-001T-P0.5 contacts and stranded 22 AWG wire, compatible with PAP-04V-S. Buy 16 × 2″ leads and remove one terminal from each, or buy 8 × 4″ leads and halve them for roughly 2″ pigtails (8 × 6″ gives roughly 3″). Allow for stripping, termination and movement slack; dry-route before choosing. Contacts are included: omit loose PA contacts. These leads have no verified gimbal torsion-life claim. |
| DigiKey Canada · 455-1596-ND | 2 housings | Specified | J9 spotlight output: 1/2, 3/4 and 5/6 are three independent LED pairs. Do not join the LED-minus wires to ground or to one another. |
| DigiKey Canada · 455-1594-ND | 2 housings | Specified | J8 Zone 7 output: +24 V, W, N, C. No GND contact. The other six zones use the manufactured upper flex. |
| DigiKey Canada · 455-1606CT-NDDigiKey alternate package ? 100 contacts | 20 fitted + spares; check stock | Check stock / package | 12 contacts for spotlight plugs and 8 for Zone 7. Live check on 13 September: the cut-tape page had only one contact available; the 100-contact strip (455-1606-100-ND) showed expected stock on 21 September. Confirm replenishment and package quantity before ordering. Omit loose contacts if a correctly specified harness includes them. Use suitable GH crimp tooling. |
| JST wire limits | 20 conductors; lengths TBD | Select compatible SKU | Must fit GH insulation OD 0.76–1.0 mm and solder to flex/LED pads. Exact product and routing remain open. Do not select thick silicone wire by gauge alone. No GH wire SKU is approved by this list yet. |
| DigiKey Canada · 455-1165-ND | 2 housings | Specified | J17 maintained ARM-switch connection. The board header is vertical, front-face mating. |
| DigiKey · 6″ ASPHSPH24K152DigiKey · 2″ ASPHSPH24K51DigiKey · 4″ ASPHSPH24K102 | 4 pigtails; choose cut plan | Confirm routed length | Two wires per ARM switch. Two double-ended 6″ leads yield four roughly 3″ pigtails when halved; otherwise use four leads trimmed from one end. Shorter 2″ and 4″ versions are linked. Choose after routing and allow termination length. Contacts are included; omit the loose PH-contact alternative. |
| DigiKey · MN11SS1G01 candidateNKK drawing | 2 switches | Select mounting / SKU | For the low-current 3.3 V ARM input (~0.33 mA), not a mains switch or motor emergency stop. NKK MN11SS1G01 is the gold-contact SPST ON–OFF candidate: 6.5 mm panel opening, 1/4-40 bushing, solder lugs. Confirm mounting clearance before buying; the listing shows supplier stock rather than DigiKey shelf stock. |
| Motor reference | 4 cables | Confirm included / pinout | One per motor; avoid duplicating included cables. Verify the actual six-contact motor pinout and retain both power and both GND contacts. DIY ZH parts are alternatives below, not additional required purchases. |
| DigiKey · 3053 RD005 red, 100 ftDigiKey · 3053 BK005 black, 100 ft | 2 pairs; length TBD | Select cut length / put-up | Fixed PSU-to-J1 feed candidate. These exact DigiKey listings are 100 ft spools, far more than two fixtures need; use suitable existing stock or request short cuts instead of buying both by default. J1 takes stripped wire directly, 6 mm strip. No mating plug. Do not substitute solid-wire 3053/1 for stranded 3053. |
| Board connections | 2 routed harness sets | Select after routing | Movement across pan and tilt needs slack, strain relief and suitable wire construction. The static arm flex stays fixed. This replaces the moving portions of the wire plan above; it is not a second complete set of wires. No generic hookup-wire life claim is assumed. |
| DigiKey Canada · HSTT-YK1 | 1 kit, if not already owned | Choose diameter per joint | 14 black 2:1 pieces, each 6″ long, in seven diameters from 1/16″ to 1/2″. Cut short sleeves for switch lugs and wire transitions; choose supplied/recovered diameter to fit each actual joint. Keep splices outside moving loops and check the rating for its location. This does not select mains splices. |
| 1 small assortment | Select SKU | Identify both ends, especially all-black pre-crimp leads and the six independent spotlight conductors. | |
| Enough for 2 fixtures | Size to cable paths | Anchor before PCB connectors and flex solder pads; do not let joints take the pull or repeated bend. | |
| Per final hole schedule | Select sizes | Protect conductors where they cross aluminum edges or holes. Size to actual openings and cable bundles. |
Power input and nonprinted mounting parts0 / 11 checked
| Product / SKU · mark when ordered | For two fixtures | Selection | Used for / purchase detail |
|---|---|---|---|
| Current board context | 2 | Select exact model | Sizing allowance, not a released enclosure-compatible SKU. Check dimensions, cooling/derating, insulation and input connection. Do not automatically substitute the old 90 W IRM-90-24ST. Initial board commissioning remains limited to 4 A. |
| 2 for socket power | Select with PSU | Confirm electrical ratings and the fixture’s mechanical support separately. A two-wire adapter provides no protective earth; do not pair it blindly with a Class I PSU. | |
| 2 input assemblies | Select with PSU | Order only the lengths not already included with the selected adapter/PSU. Gauge, insulation, temperature and input arrangement depend on that specific installation. | |
| Per actual input joins | Select with PSU | Match the adapter leads and PSU input terminal or pigtail. Include mains input fuse/holder only if required by the selected PSU installation instructions; do not copy the old bench DC fuse as the answer. | |
| 2 arrangements | Select with PSU | Prevent access to live input terminals and maintain separation from the aluminum body and low-voltage wiring. Choose the PSU and insulation arrangement together. | |
| 2 input assemblies | Select with input cable | Sized to the actual input cable and mounting opening; a low-voltage cable anchor is not automatically the correct part. | |
| 2 mounting arrangements | Resolve load path | Confirm how the fixture’s weight is supported. The adapter’s wattage rating says nothing about permissible hanging load. Buy a separate tether only if the chosen installation calls for one. | |
| Motor mounting context | Up to 16 fitted | Select lengths | Four motor output flanges, up to four screws each. Respect the actual motor’s 2.5 mm thread-entry limit; overall screw length depends on the mount. Do not inherit scaffold-specific M3 × 10 blindly. |
| Mounting context | Up to 16 fitted | Select lengths | Match the final mounts and manufacturer engagement limits. Printed gimbal parts themselves are excluded. |
| Main board | 8 mounting positions | Select heights / lengths | Four mounting holes per main PCB. Allow clearance for components on both sides; select the actual spacer and screw stack, not a generic kit as proof of fit. |
| 2 complete sets | Measure mounts | List the individual sizes after final mount dimensions are available. No extra 608ZZ bearing is required by the documented frame v8. |
Alternatives and shared bench supplies0 / 12 checked
These do not count toward the required-purchase total. When an alternative covers a required product, check that required line above too. Tools are shared and needed only if you do not already own suitable ones.
| Product / SKU · mark when ordered | For two fixtures | Selection | Used for / purchase detail |
|---|---|---|---|
| DigiKey · 100-contact strip | 16 fitted + spares; listed pack 100 | Alternative | Alternative only to the pre-crimped PA leads above. DigiKey 455-1325-100-ND is a 100-contact strip. Requires compatible stranded wire (AWG26–22, insulation OD 1.0–1.5 mm) and tooling; do not buy both routes by default. |
| DigiKey · PH loose contacts | 4 fitted + spares; check minimum 100 | Alternative | Alternative only to the pre-crimped PH leads above. DigiKey 455-1127CT-ND listing starts at 100 contacts; verify its minimum and packaging before ordering. Also needs compatible switch wire and tooling. |
| DigiKey · ZHR-6 housingsDigiKey · SZH-002T-P0.5 contacts | 4 housings + 24 contacts | Alternative | Only to replace absent supplier motor cables. Verify actual motor pinout, conductor size and duplicate power/GND contacts; AWG22 does not fit these contacts. |
| Manufacturer | Sheet as needed | Alternative | Your previous 20″ × 24″ diffusion option, instead of Yupo unless intentionally layering optical tests. |
| If supplied backing is inadequate | Conditional | Confirm thermal contact and tape backing on the actual tube. VHB 4611 is specified under the flex bands, not blanket foam underneath the LED strips. | |
| DigiKey · StarTech USB315AC1M | 1 shared cable | If not owned | Optional 1 m USB-A-to-USB-C data/charging cable for J14, if your computer has USB-A. An existing suitable data cable is enough. USB is not the fixture operating supply: provide external 24 V. Retain the normal VBUS conductor; choose a USB-C host cable instead if required by your computer. |
| DigiKey · SHR-04V-S housingDigiKey · SH contacts, strip of 100 | 1 shared set | Optional | Optional J15 service alternative. Linked housing and contacts do not include a USB-UART adapter. Use 3.3 V logic and three contacts for GND/TX/RX; leave the board power contact unconnected. DigiKey 455-2963-100-ND is a 100-contact strip, so a verified prewired harness may avoid waste. USB normally covers programming. |
| 1 shared set | If not owned | For strip pads, flex solder stations and switch leads. Follow the flex assembly temperature/process limits; the main PCB arrives assembled. | |
| 1 shared set | If not owned | GH contacts still need tooling unless buying completed harnesses. A generic JST-XH crimper does not establish compatibility with GH/PA/PH terminals. | |
| 1 shared meter | If not owned | Verify harness continuity, polarity and absence of shorts before connection. | |
| 1 shared supply | If not owned | Commissioning with controlled current and an accessible disconnect. The ARM switch does not cut motor or mains power. | |
| 1 shared instrument | If not owned | Verify spotlight housing, LED tube and PSU temperatures in the actual assembly. |
What the adversarial review changed¶
- Corrected the tape arithmetic: actual 2.46″ cut increments give 11.48′ for two fixtures with the provisional ring allowance. Ring geometry still needs a dry-fit.
- Recovered the actual spotlight configuration and housing: the bench uses warm-white XP-E2, cool-white XP-E2 and PC Amber; the documented housing is DLH-3UP-EH. A generic three-LED star may have the wrong internal connections.
- Added two omitted mounting adhesives: 1.1 mm VHB 4611 under the flex bands and 0.05 mm 467MP for the static gimbal flex. These are user-applied; they are not the factory PI stiffeners.
- Corrected the Yupo identifier: the maker lists L21-YPT153WH1114; the earlier Amazon title used YUP.
- Reduced loose-crimp purchasing: exact PA and PH pre-crimp lead options are listed. GH wire compatibility and moving-loop lengths remain unresolved.
- Separated mains integration from the old bench BOM: the PSU, socket input, insulation, retention and associated hardware must be selected together. The earlier 90 W PSU and its insulation assumptions are not an automatic fit for this revision.
The remaining selection work is concentrated in tube supplier/thermal confirmation and mounting dimensions, spotlight configuration/thermal check, PSU/input arrangement, GH wire and moving harness routing. These are open assembly decisions, not evidence that the manufactured boards have been physically validated.
Do not buy these twice¶
The factory PCBA includes the ESP32-C6, driver electronics, regulators, protection parts, C504 and all fitted board-side connectors. The old ESP32 dev kit, PCA9685 modules, ULN2803s, PicoBuck, Pololu regulator, protoboards, socket headers, JST-XH kit, XT30 adapters and bare bus wire belong to the earlier bench build. They are not required purchases here.
J1 takes bare stripped power wires; J2 takes the upper flex directly. The static gimbal stations are solder connections. J18 is expansion solder pads, not another fitted connector. J16 brake/bus hardware is not required for the initial build; decide on an energy-dissipation accessory only if commissioning establishes a need. The previous frame's extra 608ZZ bearing is also excluded.
Reference and scope¶
Connector quantities and pin functions were checked against the native main board with SHA256 starting cbb8d9fc and the corrected 241-part factory BOM, not the older hand-wired harness guide. See Doc 9’s connectors, the actual bench spotlight, and Doc 10’s flex geometry and assembly holds. Product links in the tables support identification; distributor links are not live stock or shipping guarantees.
The 120 W PSU figure is a conditional sizing allowance, with bounded LED duty and motor input assumptions. It does not release unrestricted simultaneous loads or establish enclosure cooling. Keep the current 4 A commissioning envelope until measured testing supports changes. The ARM switch is a lighting interlock, not a motor emergency stop.
