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.
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.
