Questions
How big is the Greenpill PCB?
It measures 52.1 × 20.3 mm and has 4 copper layers, 1.2 mm thick.
What parts does the Greenpill use?
33 parts, built around the STM32F103CBT6, W25Q128JVSIQ, XC6206P332MR and TS-1088R-02526. 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 Greenpill KiCad files?
From the lbthomsen/greenpill repository on GitHub, at the commit this page was made from: the board is pcb/gp.kicad_pcb and its schematic pcb/gp.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Greenpill design in my own project?
Its repository states no licence, so its author keeps all rights: ask lbthomsen before reusing the design.
