The Happymodel CrazyF405 HD is an AIO board for 1-2S whoopy s digital video transmission. The board contains a flight controller, ESCs and ELRS receiver in one.
The core of the flight controller is the F405 processor complemented by the BMI270 gyro. The CrazyF405 also includes 8MB memory for the blackbox and a barometer, which is not common on boards of this size. The board does not include an analog OSD.
The ESCs use Bluejay firmware. They can handle 12A loads and are thus suitable for motors up to size 1404. The board can be powered by 1-2S Lipo batteries. A current sensor (scale 470) is also available.
Another part of the board is an ELRS receiver. This is not connected via the SPI bus, but is a classic Happymodel EP receiver connected via UART. It can thus be fully configured as any external ELRS receiver. The receiver is connected via UART2. After disconnecting the pads, the ELRS receiver can be disconnected and use the UART to connect another device.
