Questions
How big is the SimpleProg2.1 KiCAD PCB?
It measures 21.9 × 47.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SimpleProg2.1 KiCAD use?
36 parts, built around the STM32F103CBT6, TPLP5907MFX-3.3, YZ76615070R-08025-01 and K3-2268D-F1. 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 SimpleProg2.1 KiCAD KiCad files?
From the BiggiePete/SimpleProg2.1 repository on GitHub, at the commit this page was made from: the board is SimpleProg2.1_KiCAD/SimpleProg2.1_KiCAD.kicad_pcb and its schematic SimpleProg2.1_KiCAD/SimpleProg2.1_KiCAD.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SimpleProg2.1 KiCAD design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
