README
README.mdThis is a Bluepill pinout-compatible devboard for the STM32F405RGT6 LQFP-64 microcontroller.
It uses all through-hole parts except for the microcontroller
and is intended to be an alternative that is easier to assemble
should the Bluepill not be available or suitable.

Questions
How big is the STM32alt PCB?
It measures 25.7 × 78.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the STM32alt use?
30 parts, built around the STM32F405RGT6 and LM1117-3.3. 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 STM32alt KiCad files?
From the profdc9/STM32F4ThruPill repository on GitHub, at the commit this page was made from: the board is STM32alt.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the STM32alt design in my own project?
Its repository states no licence, so its author keeps all rights: ask profdc9 before reusing the design.
