Product Overview
A Helio Spring for minis! This Helio Spring IMU-F Mini is a 20x20mm flight controller with impressive specs. Capable of true 32khz processing, dual processors with F3, and F4, 5 UARTs, OSD, LC filter and much more.
A truly beastly mini controller from Helio.
Next Level Innovation
- Supported by multiple open source flight controller software including ButterFlight’s 3.3+ most current technologies
Natively Fast
- True 32khz processing without overclocking
- More than capable of 32khz PID-loop speeds even on an F4.
IMU-F
- 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
Helio Gyro
- The hardware contains both an f3 (IMU-F) and an f4 and the IMU 20601.
