BetaFPV F4 1S 5A AIO Brushless Flight Controller

Attention! The BetaFPV F4 1S 5A AIO Brushless Flight Controller has been discontinued. The new Matrix 3in1 4in1 series, as well as Matrix 5in1, are available for order.

The F4 1S 5A AIO Brushless Flight Controller is back in stock with new and updated features. The new board integrates a Serial ExpressLRS 2.4G receiver. Compared with the original built-in SPI ELRS 2.4G receiver, it could easily flash the latest official ELRS firmware such as V3.0. In addition, we have updated the FC with a high quality BMI270 gyro, BB51 ESC hardware with Bluejay ESC firmware and 8MB Betaflight Blackbox flash.

Treat yourself with the Serial ExpressLRS 2.4G receiver, which can be updated via Wi-Fi or the Betaflight serial port. Pilots can conveniently flash any version of ELRS RX firmware and can especially flash ExpressLRS V3.0 without updating the flight controller firmware.

The SPI Frsky version board reserves the SBUS port and UART, which are available for the SBUS protocol receiver or other external receivers.

The built-in 8 MB flash memory chip is dedicated to Blackbox journaling. It is a very powerful tool for configuring and troubleshooting your FPV drone.

Special design with weight of 3.64g (classic) and 2.96g (lightweight), reasonable layout and easy to assemble. With a mounting hole size of 26*26mm, it is fully compatible with the mounting frame in the current market.

The Light version requires soldering the motor wires directly to the panel, which reduces the resistance to increase the motors' current. It also features motor pin connectors for ease of use.
