F405 V5 2-4S 25x25 AIO Flight Controller with 8Bit 20A ESC



In stock
  • Based on the F405 2-4S 20A Brushless Flight Controller V4, the F405 4S 20A Toothpick Brushless Flight Controller V5 applies a new ICM42688 gyro and ESC chip that comes with BLUEJAY ESC firmware so it supports bidirectional D-shot. In addition to plug&play ports for the receiver and HD Digitial VTX the same as the V4 board, the V5 board is made with a rational layout for easy solder and preventing solder from jumping to another pad and shorting components.


    • Not only is the flight controller board made with a rational layout but it is also designed with larger solder pads. It is very easy for pilots to solder external electronics.
    • The flight controller is capable of handling 20A continuous current and reaching 25A peak current due to high-quality MOSFETs.
    • Soldering motor wires to pad directly allows lower resistance for more current on motors. Besides, solder pads are reinforced by thick copper and edge plating process, ensuring a solid value and durable use.
    • Reserving the UART ports layout, UART3 for RX, UART4 for HD digital VTX, UART6 for Analog VTX and UART1 for spare use, it is more convenient for pilots to solder.
    • Come with a 25.5*25.5mm whoop mounting pattern, this board can be added to both the toothpick drone and the cinematic whoop quadcopter frame.

    Connecting External RX/HD Digital VTX

    F405 4S 20A FC V5 integrates the Plug & Play port for the external RX and HD digital VTX, and there will be a 4-pin connector for RX and a 6-pin connector for HD digital VTX in the package. Thus, we highly recommend pilots use the port to save the solder work.
