Questions
How big is the Payload pcb PCB?
It measures 127 × 76.2 mm and has 4 copper layers, 1.59 mm thick.
What parts does the Payload pcb use?
114 parts, built around the MCP2562-H/P, SC0915, LTC2990IMS#TRPBF and MCP2200-I/SS. 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 Payload pcb KiCad files?
From the austindriggs/urc-payload-pcb repository on GitHub, at the commit this page was made from: the board is payload-pcb.kicad_pcb and its schematic can.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Payload pcb 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).
