The F405 4S 20A AIO 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 and play ports for the receiver and HD Digitial VTX, 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, the 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 like Pavo25 & X-knight 35.

Comparison to F405 2-4S 20A V4 FC

BETAFPV upgraded the F405 2-4S 20A V4 board to V5 by adopting ICM42688 gyro instead of MPU6000 and adding some new features. ICM42688 gyro works great in most cases. Except for the gyro, the V5 board comes with a completely new ESC firmware that supports bidirectional D-shot. The way to connect motors changed and is solder-able only on the V5 board. Besides the V5 FC board features high-quality material for stability and durability. The below pictures show the difference between the two flight controllers.

Note: F405 4S 20A FC V5 is available to flash both BLHeli_S and BLUEJAY ESC firmware and it comes with default BLUEJAY firmware. The main difference is that the BLUEJAY firmware supports bidirectional D-shot, while BLHeli_S does not support it.
