BetaFPV Matrix G4 5in1 V2 (FC+ESC+ELRS RX+VTX)

BetaFPV Matrix G4 5in1 is an AIO board designed for 1S TinyWhoppies and other small FPV drones. The board includes a flight controller, ESCs, RC receiver, analog video transmitter, and OSD chip. It is mounted on a 1 mm thick PCB for durability. The board is available in two variants - with connectors for easy motor connections or without connectors for soldering motors. It is secured at only 3 points. The front side does not attach to the frame, reducing the chances of damage to the flight controller during plastic frame deformation.

The flight controller is equipped with a STM32G473 processor. There is also 16 MB memory for blackbox. The integrated 4in1 ESCs can handle up to 12 A in the second version and use Bluejay firmware.

The built-in 5.8 GHz video transmitter allows transmission of analog video with power options of 25/100/200/400 mW. Thanks to SmartAudio protocol support, configuring the transmitter is easy via Betaflight. For indoor flying, it is recommended to use 25–100 mW to reduce heat and battery consumption. The antenna connects via a u.FL connector. RC transmission is ensured by the integrated ELRS 2.4 GHz receiver connected via UART. The UART connection is available on the board, and if necessary, the integrated receiver can be disconnected and an external one connected. The internal ELRS receiver uses a wired antenna powered directly from the board.

Due to the lack of IMU ICM42688, the boards contain the IMU chip ICM42622, LSM6DSV16X or LSM6DSK320X, which is not supported in the official Betaflight firmware. Firmware for flight controllers with this IMU is available for download here.
