Questions
How big is the HorseSense PCB?
It measures 35 × 55.3 mm and has 4 copper layers, 1.6 mm thick.
What parts does the HorseSense use?
71 parts, built around the BGA824N6E6329XTSA1, ESP32-S3-WROOM-1-N16R8, MAX-M8Q-0 and MAX86141ENP+T. 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 HorseSense KiCad files?
From the Philippe12/HorseSense repository on GitHub, at the commit this page was made from: the board is horsesense.kicad_pcb and its schematic capteur.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the HorseSense design in my own project?
Its repository states no licence, so its author keeps all rights: ask Philippe12 before reusing the design.
