BetaFPV F411 4S 20A Toothpick Brushless Flight Controller V5 BLHeli_S (BMI270)

As a continuance of the F411 chip, the V5 FC board is upgraded from the F4 20A V3 FC board. F411 4S 20A Toothpick Brushless Flight Controller V5 adopts BMI270 gyro instead of MPU6000 on V3 board. With two integrated plug&play ports for receiver and HD digital VTX, it is easy to install and requires less solder work. Besides, the board is a solid value for durable use thanks to the high-quality PCB material and enhanced production process.

Bullet Point

• With a large pad to solder, it is easy to solder external electronics. In addition, the V5 board features plug&play ports for the receiver and HD digital VTX, which requires less solder work for convenient installation.
• High-quality MOSFETs are applied to F411 4S 20A FC V5 to handle 20A continuous current and reach 25A peak current.
• The motor solder pads are reinforced by thick copper and edge plating technology, allowing lower resistance for more current on motors.
• F411 4S 20A FC V5 reserves the UART ports layout, UART1 for RX, UART2 for DJI OSD or Analog VTX, and UART6 for spare usage, 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.

Note: F411 4S 20A FC V5 is available to flash both BLHeli_S and BLUEJAY ESC firmware and it comes with default BLHeliI_S firmware. The main difference is that the BLUEJAY firmware supports bidirectional D-shot, while BLHeli_S does not support it. 

Comparison to F411 4S 20A V3 FC

We upgraded the F411 4S 20A V3 board to V5 by adopting BMI270 gyro instead of MPU6000 and adding some new features. BMI270 gyro works great in most cases, especially in low frequency. Unlike the V3 board that supports JST1.25 connectors, the motor solder pads on V5 board are solderable only and reinforced by thick copper and edge plating technology, allowing lower resistance for more current on motors. Besides, the V5 FC board features high-quality material for the stability of the solder and durability of use. The below pictures show the difference between the two flight controllers.
