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

BETAFPV Matrix G4 5IN1 V1 is an AIO board designed for 1S TinyWhoops and other small FPV drones. The board integrates a flight controller, ESCs, RC receiver, analog video transmitter, and OSD chip. It is built on a 1mm thick PCB for improved durability. For easy motor connection, the board is equipped with plug-in connectors, making it especially suitable for beginner and recreational pilots.

The flight controller is powered by an STM32G473 processor and an ICM42688P gyro. It also features 16MB of blackbox memory. The integrated 4-in-1 ESCs support up to 5A and run on Bluejay firmware.

The built-in 5.8GHz VTX supports output power levels of 25/100/200/400 mW. With SmartAudio support, the VTX can be easily configured through Betaflight. For indoor flying, 25–100 mW is recommended to reduce heat and battery consumption. The antenna connects via a u.FL connector. RC control is provided by an integrated 2.4GHz ELRS receiver connected via UART. The UART pads remain available, allowing the onboard receiver to be disabled and replaced with an external one if needed. The internal ELRS receiver uses a direct-soldered wire antenna.
