A flight controller with a built-in Serial ELRS receiver and 4-IN-1 Blheli_S 12A ESC specially developed for Digital HD FPV, which removes the analog OSD chip 7456, optimizes the PCB layout, and supports 1-2S Lipo/LiHV lithium batteries, very Suitable for Digital HD Tinywhoop/Cinewhoop/Toothpick and other small FPV drones. The flight controller uses the F405 chip, supports Betaflight/INAV firmware, has 3 sets of complete UARTs available, and integrates a BMP280 barometer and 8Mbp blackbox, which greatly enhances the playability of the flight controller.

Usage Instructions:
If bound to radio but having trouble seeing stick movement in Betaflight, then you may need to turn off the “Model Match” factory setting in the ELRS web GUI.
For original factory 4.3.2 version firmware, if you want to use BMP280 barometer, please connect to betaflight configurator and then move to CLI command, then type the following command:
resource I2C_SDA 2 B11
set baro_bustype = I2C
set baro_i2c_device = 2
2. Add BARO_BMP280 to custom defines
3. Flash the board
4.Configure resources for external BARO device for the flight controller in CLl:
resource I2C_SDA 2 B11
set baro_bustype = I2C
set baro_i2c_device = 2
Package Includes:
- 1x Happymodel CrazyF401 Whoop AIO Flight Controller with 12A BLHELI_S 4-in-1 ESC and ELRS 2.4GHz Rx
