This board is ideal for the smallest setup possible with no dedicated power board.
BOM
| Reference | Part desc / number | Notes |
|---|---|---|
| J1 | 6-pin SMD Type C connector - Mouser / LCSC | |
| J2 | Molex 53261-0271 - Mouser | |
| - | Picoblade Cable assembly - Preassembled - Mouser (60cm length) / LCSC - housing + LCSC - terminal | Need one of these for each emitter board |
| F1 | 0805 PTC - Mouser / LCSC | Overcurrent protection |
| D1-3 | IR LED - 940nm - Mouser | |
| D4 | Status LED - Mouser / LCSC | Optional |
| R1 | 7-120R 0805 - Mouser / LCSC | Value depends on your LEDs - 7-10R work well with SFH-4547 |
| R2,R3 | 5.1K 0603 - Mouser / LCSC | Required if powering from C-C cable |
| R4 | 1K 0603 - Mouser / LCSC | Required for status LED |
| SW1 | DPDT - Mouser / LCSC | Optional, but recommended |

Questions
How big is the Sensorstrip power-42-square PCB?
It measures 50 × 22 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sensorstrip power-42-square use?
17 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Sensorstrip power-42-square KiCad files?
From the eatnooM/sensorstrip repository on GitHub, at the commit this page was made from: the board is sensorstrip-power-42-square/sensorstrip-power-42-square.kicad_pcb and its schematic sensorstrip-coupler/sensorstrip-coupler.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sensorstrip power-42-square design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
