Questions

How big is the Ir led PCB?

It measures 50 × 50 mm and has 8 copper layers, 1.6 mm thick.

What parts does the Ir led use?

5 parts, built around the DF40C-100DP-0.4V(51). 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 Ir led KiCad files?

From the box1o/woki-camera repository on GitHub, at the commit this page was made from: the board is boards/04-ir-led/ir_led.kicad_pcb and its schematic boards/01-power/power.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Ir led design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
