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.

Bullet Point

• 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 like Pavo25 and X-knight 35.
