The Helio Spring IMU-F Flight Controller features an onboard F3 based co-processor chip which transparently filters the gyro signal at 32khz before passing it onto the flight controller in quaternion form at 16khz. This leaves more processing power available to the flight controller.
Supported by multiple open source flight controller software including ButterFlight’s 3.3+ most current technologies
True 32khz processing without overclocking
Never before seen IMU-f system an advanced inline discrete filtered gyro that is transparent to the flight controller
With a super clean discrete filtered gyro, more processing power is available for flight controller logic and future feature updates without causing slowdown or issues during flight
The hardware contains both an f3 (IMU-F) and an f4. The gyro is a IMU 20601.
