Questions
How big is the PythonsHead PCB?
It measures 45 × 79.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PythonsHead use?
92 parts, built around the CC1101RGP, ST1S10PHR, BAT54WS and MMBT2222. 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 PythonsHead KiCad files?
From the Kreyl/PythonsHead repository on GitHub, at the commit this page was made from: the board is PythonsHead_hw/PythonsHead.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the PythonsHead design in my own project?
Its repository states no licence, so its author keeps all rights: ask Kreyl before reusing the design.
