Oooooooohhhh, STM32 chipsets are a rabbit hole and a half to which I am not as familiar with, compared to the 10+ years of knowledge I have on Microchip's chipsets. STM32 chipsets are largely uncharted territory for me, so there is a learning curve here (to which, I would love to take on).

Here is where I would start:

• STM32F103
• STM32F405
• STM32F722

I would like to add in STM32H745 support as well. However, the board support package for this chipset is not currently available to the Arduino IDE.

I have cherry-picked these four chipsets, because these are the same chipsets used in most drone flight controllers today, and are available as development boards as well.

This will be an interesting feature to have, as the more hardware agnostic CRSF for Arduino is, the better it will be.
