BetaFPV F405 4S 20A Toothpick Brushless Flight Controller V5 BLHeli_S (ICM42688)

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 .
