SIYI N7 Autopilot Flight Controller — STM32H743, Dual IMU, PX4 & ArduPilot, 2–14S, Industrial UAV & Robotics
The SIYI N7 is a professional-grade autopilot flight controller engineered for industrial UAVs, heavy-lift multirotors, fixed-wing aircraft, VTOL platforms, and robotics applications. Built on the STM32H743 ARM Cortex-M7 processor with a dual IMU configuration (ICM-42688-P + ICM-20689) and dual barometers, the N7 provides the redundancy and sensor reliability demanded by industrial and commercial UAV operations. Full support for both PX4 and ArduPilot open-source firmware gives operators and integrators maximum ecosystem flexibility. A wide 2–14S input voltage range and integrated power module make the N7 compatible with everything from compact hexarotors to large industrial platforms. Available with or without the SIYI M9N GNSS module.
Key Features
- STM32H743 ARM Cortex-M7 Processor — High-performance MCU running at up to 480MHz; delivers the processing headroom required for demanding industrial autopilot workloads, sensor fusion, and real-time control loops
- Dual IMU: ICM-42688-P + ICM-20689 — Two independent 6-axis IMUs provide sensor redundancy; if one IMU fails or is degraded by vibration, the autopilot continues operating on the secondary sensor — critical for industrial and professional UAV reliability
- Dual Barometers — Redundant barometric altitude sensing for improved altitude hold accuracy and failsafe reliability in demanding flight environments
- PX4 & ArduPilot Dual Ecosystem — Full support for both PX4 and ArduPilot firmware; configure via QGroundControl (PX4) or Mission Planner (ArduPilot); access the complete ecosystem of autonomous flight modes, waypoint missions, geofencing, and advanced failsafes
- Wide 2–14S Input Voltage — Accepts 2S through 14S LiPo input; compatible with small multirotors through large industrial heavy-lift UAV platforms and high-voltage fixed-wing aircraft
- Integrated Power Module — On-board power module simplifies wiring and power distribution; reduces external component count for cleaner industrial airframe integration
- M9N GNSS Module (Optional) — SIYI M9N multi-constellation GNSS module available as a bundle; provides reliable GPS position hold, RTH, waypoint navigation, and geofencing for autonomous missions
- Industrial & Robotics Applications — Designed for professional UAV integrators, industrial inspection, agriculture, heavy-lift, and ground robotics platforms requiring a proven open-source autopilot with redundant sensors
Variant Guide
- N7 + GPS — SIYI N7 autopilot with SIYI M9N GNSS module included; ready for autonomous GPS flight out of the box
- N7 (No GPS) — SIYI N7 autopilot only; add your own GNSS module or use in non-GPS flight modes
