Questions
How big is the Playduino sheep tester PCB?
It measures 123.6 × 90.8 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Playduino sheep tester use?
201 parts, built around the B0524S-2WR3, B0512S-2WR3, ADS1115IDGS and ULN2003ADRG. 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 Playduino sheep tester KiCad files?
From the playduino/sheep-tester repository on GitHub, at the commit this page was made from: the board is playduino_sheep_tester/playduino_sheep_tester.kicad_pcb and its schematic playduino_sheep_tester/analog inputs.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Playduino sheep tester 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).
