Questions
How big is the Skin optoelectronics module PCB?
It measures 20.7 × 25.9 mm and has 4 copper layers, 1 mm thick.
What parts does the Skin optoelectronics module use?
80 parts, built around the ATTINY416-MN, EFM8BB10F2G-A-QFN20, 74LVC1G125 and OPA340NA. 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 Skin optoelectronics module KiCad files?
From the Roboy/roboy-skin-electronics repository on GitHub, at the commit this page was made from: the board is skin_optoelectronics_module/skin_optoelectronics_module.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Skin optoelectronics module design in my own project?
Its repository states no licence, so its author keeps all rights: ask Roboy before reusing the design.
