BetaFPV Toothpick F405 2-4S AIO 20A BLS V5

Revolutionary Flight Controller for FPV Pilots

Introducing the BetaFPV Toothpick F405 2-4S AIO 20A BLS V5, the ultimate flight controller designed specifically for FPV pilots seeking performance and reliability. This advanced flight controller integrates cutting-edge technology to enhance your flying experience, making it perfect for both beginners and seasoned pilots alike.

Based on the F405 2-4S 20A Brushless Flight Controller V4

The F405 4S 20A Toothpick Brushless Flight Controller V5 features a new ICM42688 gyro and ESC chip, equipped with BLUEJAY ESC firmware that supports bidirectional D-shot. The V5 board is designed with a rational layout, ensuring easy soldering and preventing solder from jumping to other pads, which could short components.

Key Features

• Rational Layout: The flight controller board is designed with larger solder pads for easy soldering of external electronics.
• High Current Handling: Capable of handling 20A continuous current and reaching 25A peak current due to high-quality MOSFETs.
• Direct Motor Connection: Soldering motor wires directly to the pad reduces resistance for improved motor performance.
• Convenient UART Ports: Reserved layout for UART ports (UART3 for RX, UART4 for HD digital VTX, UART6 for Analog VTX, and UART1 for spare use).
• Compact Size: 25.5*25.5mm whoop mounting pattern for compatibility with toothpick drones and cinematic whoop quadcopter frames like Pavo25 and X-knight 35.
