caution
AT32F435 MCU
The AT32F435 MCUs are only supported in Betaflight versions 4.5 and newer. Older versions of Betaflight do not have a target for it, and do not work on this platform.
Onboard LEDs
The flight controller has 28 RGB LEDs onboard, connected in parallel to the LED signal connection, and powered from the onboard regulator. Bridging the LED_EN pads will connect the signal line to the LEDs, enabling full control of the LEDs from the flight controller.
