Questions
How big is the ProtogenBackpackPCB PCB?
It measures 70.6 × 84.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ProtogenBackpackPCB use?
28 parts, built around the TMC2209SILENTSTEPSTICK, DS3231MZ/V+, TLC59108F_PW_20 and SKRKAHE020. 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 ProtogenBackpackPCB KiCad files?
From the MyloWhylo/ProtogenPCBs repository on GitHub, at the commit this page was made from: the board is BackpackPCB/ProtogenBackpackPCB.kicad_pcb and its schematic BackpackPCB/ProtogenBackpackPCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ProtogenBackpackPCB 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).
