The F4 1S 5A AIO Brushless Flight Controller is back in stock with new and upgraded features. The new board integrates Serial ExpressLRS 2.4G receiver. Compared with the original built-in SPI ELRS 2.4G receiver, it could flash the newest ELRS official firmware like V3.0 easily. Also, we updated the FC with high-quality BMI270 gyro, BB51 ESC hardware with Bluejay ESC firmware, and 8MB Betaflight Blackbox flash.
Two version choices for the FC board. Weighing only 2.96 grams, the Light version comes with NO motor connectors soldered. Therefore, pilots could directly solder the motor cables to the FC board, getting an ultimate lightweight drone for fast speed FPV racing.
Come with a Serial ExpressLRS 2.4G receiver, which can be updated via Wi-Fi or Betaflight serial passthrough. It is convenient for pilots to flash any version of ELRS RX firmware and especially can flash ExpressLRS V3.0 without updating flight controller firmware.
The SPI Frsky version board reserves an SBUS port and a UART port, which is available for the SBUS protocol receiver or other external receivers.
Built-in an 8MB flash memory chip dedicated to Blackbox logging. It’s an extremely powerful tool for tuning and troubleshooting an FPV drone.
Particular design with a weight of 3.64g (Classical) and 2.96g (Light), reasonable layout, and easy to build. With a 26*26mm mounting hole size, it is fully compatible with the whoop frame in the current market.
The Light version requires soldering motor wires to the pad directly, which allows lower resistance for more current on motors. It also comes with motor pin connectors for convenience to use.
