Questions
How big is the Qfmu PCB?
It measures 244 × 244 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Qfmu use?
236 parts, built around the EFM32GG11B120F2048GQ64-B, AS179-92LF, MICRF113YM6-TR and MICRF219AAYQS-TR. 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 Qfmu KiCad files?
From the steewbsd/quincy repository on GitHub, at the commit this page was made from: the board is hw/qfmu/qfmu.kicad_pcb and its schematic hw/qfmu/mcu.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Qfmu design in my own project?
Its repository states no licence, so its author keeps all rights: ask steewbsd before reusing the design.
