Caddx F4 AIO ELRS Flight Controller

The Caddx F4 AIO ELRS is the all-in-one board from the Caddx Gofilm 20 cinewhoop: an F405 flight controller, a 20A 4-in-1 ESC and an ELRS 2.4GHz receiver on one 25.5 x 25.5 mm board weighing 5.3 g. Use it as a direct replacement in a Gofilm 20, or as a light brain for your own 2-3 inch digital cinewhoop or micro on 3S-4S.

Key features

• Built-in ELRS V3.0 receiver on a UART, with no separate receiver to wire

• ICM42688 gyro and BMP280 barometer

• 8 MB onboard blackbox for flight logs

• Runs Betaflight on the CADDXF4_AIO_ELRS target

• Made for digital video: there is no analog OSD chip, so it is not suited to analog builds

The receiver binds only to ELRS 2.4GHz radios; FrSky, Crossfire and DJI FPV remotes will not work with it. The 20A-per-motor rating suits 2-3 inch builds, not 5-inch quads. In the Gofilm 20 it pairs with the Walksnail Moonlight kit.
