Questions
How big is the Snaphat pcb PCB?
It measures 100 × 68.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Snaphat pcb use?
116 parts, built around the MIC2250-1YD5-TR, AP9101CAK6-ABTRG1, LIS2DW12TR-MS and MCP73871T-2CCI/ML. 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 Snaphat pcb KiCad files?
From the marchmare/snaphat-pcb repository on GitHub, at the commit this page was made from: the board is main_board/main_board.kicad_pcb and its schematic main_board/main_board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Snaphat pcb design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
