VERSIONS:
- The F405_pill_V1.0 has been deprecated.
- The F405_pill_V1.11 has an additional 100nF cap on the input to PA4 (throttle) and we suggest you use this for ordering.
V1.1 changes
- Xtal caps from 18pF to 12pF
- Separate the two LEDs from the single resistor
- CAN spike protection
- RC between GND and pb12 to stop false trips
- PC12->PA15 to drive LED
- Increased functionality of several header pins
- Review this document for pin changes
REVISION REQUEST
- Jumper to disable CAN termination resistor on bottom side of board

Questions
How big is the F405 pill PCB?
It measures 54.1 × 19.4 mm and has 4 copper layers, 4.69 mm thick.
What parts does the F405 pill use?
50 parts, built around the HT7550, LM1117-3.3 and TYPE-C-31-M-12. 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 F405 pill KiCad files?
From the davidmolony/F405_pill repository on GitHub, at the commit this page was made from: the board is F405_pill_V1.11/F405_pill.kicad_pcb and its schematic F405_pill_V1.1/F405_pill.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the F405 pill design in my own project?
Its repository publishes it under the BSD-3-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
