FIRSTLEGENDS at checkout.Based on the F405 2-4S 20A Flight Controller V4, the F405 4S 20A Toothpick 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-and-play ports for the receiver and HD Digitial VTX, the same as the V4 board, the V5 board is made with a more rational layout for easy solder and preventing solder from jumping to another pad and shorting components.
Check out all our whoop flight controllers, and all our BetaFPV gear!
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.
