Skydroid S3 Flight Controller — STM32H7, BMI088 IMU, 2S–18S, GPS & RTK Options
The Skydroid S3 is a high-performance flight controller built around the STM32H7 series main control chip for powerful, reliable flight management across multirotors, fixed-wing UAVs, RC boats, and RC cars. The integrated automotive-grade BMI088 IMU features an elaborate vibration-damping design that ensures stable and accurate attitude data collection even in demanding flight environments. A dedicated barometer and gyroscope round out the sensor suite for precise altitude hold and orientation tracking. The S3’s housing includes screw-mount holes for simplified, secure installation. Available in standard (S3), GPS, Mini, Mini GPS, and RTK configurations to match your platform and mission requirements.
Key Features
- STM32H7 High-Performance Processor — Latest-generation STM32H7 ARM Cortex-M7 MCU; delivers the processing headroom needed for complex flight algorithms, fast PID loops, and real-time sensor fusion
- Automotive-Grade BMI088 IMU — Bosch BMI088 6-axis IMU with purpose-designed vibration isolation; optimized for UAV environments where motor vibration can compromise sensor accuracy
- Wide Voltage Range: 2S–18S — Supports 2S through 18S LiPo input; compatible with everything from small multirotors to large industrial UAVs and high-voltage fixed-wing platforms
- Integrated Barometer & Gyroscope — On-board barometer for altitude hold and gyro for stable rate and angle mode flight; no external sensors required for basic operation
- Screw-Mount Housing — Reinforced housing with dedicated screw mounting holes; simplifies installation and provides a secure, vibration-resistant connection to the airframe
- GPS & RTK Variants — Standard variants for general FPV and UAV use; GPS variants add position hold and return-to-home; the S3 RTK variant provides centimeter-level positioning for precision agriculture, survey, and professional UAV operations
- Mini Form Factor Options — S3 Mini and S3 Mini GPS offer the same STM32H7/BMI088 core in a smaller footprint; ideal for compact multirotors and builds where board space is at a premium
- Multi-Platform Compatible — Supports multirotor (quad, hex, octo), fixed-wing, RC boat, and RC car configurations
