Questions
How big is the Rpi absorbance PCB?
It measures 39.2 × 56.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rpi absorbance use?
33 parts, built around the R-78B5.0-1.5L, DRV8825PWP, TCA9406DCUR and ZTX692BSTZ. 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 Rpi absorbance KiCad files?
From the jnod/rpi_absorbance repository on GitHub, at the commit this page was made from: the board is rpi_absorbance.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rpi absorbance design in my own project?
Its repository states no licence, so its author keeps all rights: ask jnod before reusing the design.
