STD Acci FPV Flight Controller - Betaflight STM32F405 / AT32F435
Mode:
STM32F405 & AT32F435 Flight Controller for Betaflight firmware drones.
Yes, you can use any of those CPU with the same board. AT32 is more powerful and cheap but Betaflight support is in early stages.
The main idea of this project is to learn and play while designing a functional F4 Flight Controller compatible with Betaflight firmware.
Specs
Version RC 1.1.2 is TESTED.
Version RC 1.1 is TESTED.
Already tested:
