The AT32F4 doesn’t just offer better bang for your buck compared to the standard STM32 MCU; it blasts the competition right out of the sky. It delivers performance that rivals the STM32 F4, and comes tantalisingly close to matching the STM32 F7. And the best part? It does all this without making your wallet weep.

This flight controller runs Betaflight. Yes, it requires a custom target for now, but don’t let that make your propellers droop. Betaflight 4.5 is on the horizon, and it should support the AT32 based flight controller natively. All you need is a dash of patience, and you’ll soon be receiving firmware updates directly from NeutronRC.

Please note, that official support will be added to Betaflight soon, for now you will need to download the firmware release and config tools.
