Questions
How big is the Dev board PCB?
It measures 45.7 × 42.2 mm and has 6 copper layers, 1.6 mm thick.
What parts does the Dev board use?
40 parts, built around the MCP3202-CI/P, NCP114ASN280T1G and DT1042-04SO-7-ES. 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 Dev board KiCad files?
From the ericpearson1313/tt_pump_out_chip repository on GitHub, at the commit this page was made from: the board is pcb/dev_board.kicad_pcb and its schematic pcb/dev_board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dev board 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).
