I am planning to use stm32 ( blue pill) to control the esc. It is 3.3v only. Will it work with cheap focer?

charclo commented 3 years ago

The cheap focer also uses an stm32, so 3,3V is perfect

astra404 commented 3 years ago

Good to hear. As I understand focer is also 5v compatable. But logic output is at 3.3v range. Is that correct?

shamansystems commented 3 years ago

The CFOC2 is capable of supplying 5V to accessories but all of the logic is 3.3V.
