SpeedyBee F405 V4 FC

Product detailed description

The new version of the SpeedyBee FC in F405 V4. The MCU on the FC remains the same STM32F405 as in V3, but the gyro has changed from BMI270 to ICM-42688P. Optimized gyro power filtering. This new gyro coupled with improved surge protection and dedicated filtering capacitors for filtering will minimize interference and guarantee cleaner gyro data and simplify PID/filter tuning. The V4 version offers native support for DShot on all 8 motor outputs, making it fully compatible with iNav.

This stack is affordable and suitable for all types of FPV drones - from racing, freestyle to long range copters
