Description
The BetaFPV V1 F4 2-3S AIO is the perfect choice for modern Whoop/Toothpick builds. Featuring an F4 AIO Flight Controller and 20A 4-in-1 ESC with ELRS serial, this setup guarantees smooth, consistent performance. It features a dual BEC solution that delivers stable power outputs of 9V/betaflight/betaflight/releases/tag/4.4.1
ESC Firmware
With BB51 ESC solution, F4 2-3S 20A AIO FC V1 is based on BLHeliSuite16714903 with Bluejay ESC firmware, it supports bidirectional D-shot and RPM filtering in Betaflight, offers 24KHz, 48KHz, and 96KHz fixed PWM frequency for options, and custom start-up melodies. F4 2-3S 20A AIO FC V1 default factory setting is 48KHz and it doesn’t recommend upgrading the 96KHz, or it might cause an error in the motor idle setting, not spinning when disarmed.
DO NOT flash the firmware with a shorter interval, otherwise, there will be a certain chance of stalling and burning the flight controller.
