The BETAFPV F405 4S Toothpick Brushless Flight Controller V5 is a significant upgrade from the V4 version, offering advanced features that make it perfect for high-performance toothpick drones. Equipped with a powerful ICM42688 gyro and a new ESC chip that supports Bluejay firmware, this flight controller is optimized for bidirectional D-shot and ensures smooth and responsive control during flight.
The BETAFPV F405 4S 20A V5 offers a more rational layout and larger solder pads for easy assembly and minimal risk of solder jumping. It supports 20A continuous current and up to 25A peak current with high-quality MOSFETs, delivering excellent power to motors. The board is designed with integrated Plug & Play ports for HD Digital VTX and external RX, making it easy to set up and reducing the need for extensive soldering.
This V5 version also features a 25.5x25.5mm whoop mounting pattern, ideal for both toothpick drones and cinematic whoops like the Pavo25 and X-Knight 35. With its built-in 5V 3A BEC and current sensor, the flight controller is a reliable choice for serious FPV pilots looking for performance and durability.
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.
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.
Comparison to F405 2-4S 20A V4 FC
We 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 solderable 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: The F405 2-4S 20A Flight Controller V4 with BMI270 gyro will be available for purchase for a period of time.

Connecting External RX/HD Digital VTX
F405 4S 20A FC V5 integrates the Plug & Play port for the external RX and HD digital VTX, and there will be a 4-pin connector for RX and a 6-pin connector for HD digital VTX in the package. Thus, we highly recommend pilots use the port to save the solder work.
FC & ESC Firmware
The default firmware is including CLI dump file. But if you flash firmware from the Betaflight configurator official site, please flash a CLI dump file for F405 4S 20A FC V5. We offer the default firmware and CLI dump file to download.
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. Here are the download links for two firmware.
Here are the download links for ESC firmware. Please configure the BLUEJAY firmware through ESC - Configurator or Bluejay Configurator software.
We offer BLHeli_S ESC firmware for pilots. Please configure the BLHeli_S ESC firmware through BLheliSuite, BLHeli - Configurator, or ESC - Configurator software.
