CrazyF405HD ELRS 1-2S AIO FC built-in UART ELRS receiver and 12A BLHELI_S ESC
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.

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
