F405 Pill for running VESC based motor control from a Black/Blue Pill footprint

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

* Jumper to disable CAN termination resistor on bottom side of board

F405 pill: common questions

What microcontroller does the F405 pill use?

The F405 pill is built around the STM32F405RGTX, from the STM32 family.

How big is the F405 pill PCB?

The F405 pill measures 54.1 × 19.4 mm, has 4 copper layers and is 4.69 mm thick.

How many components are on the F405 pill?

46 components, from 30 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the F405 pill design files?

From the davidmolony/F405_pill repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the F405 pill design in my own project?

Yes, under the terms of its BSD-3-Clause license, which davidmolony chose for the repository.

Can I test firmware for the F405 pill without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
