SIYI N7 Autopilot Flight Controller with 2-14S Power Module

The SIYI N7 is a high-performance autopilot flight controller engineered for multirotors, fixed-wing aircraft, VTOLs and commercial UAVs. Built around a powerful STM32H743 main processor (480 MHz) and an STM32F103 failsafe co-processor, it easily manages complex autonomous missions under both ArduPilot and PX4 ecosystems. Designed for exceptional reliability, the N7 features dual redundant IMUs, an integrated IST8310 compass and a rugged aluminium case with an internal shock-absorption structure. Every package includes a 2-14S power module for seamless integration with heavy-lift and agricultural setups.

Key features

• Dual redundant IMUs (BMI088 and ICM20689) alongside an MS5611 barometer and IST8310 compass

• Includes a dedicated power module supporting 2-14S LiPo inputs (7.4 V to 59.6 V)

• Native ecosystem compatibility with ArduPilot and PX4 firmware

• Extensive peripheral connectivity with 4 UARTs, 3 I2C ports and a CAN bus

• 13 total PWM outputs (8 standard, 5 programmable) for complex multirotor and fixed-wing builds

• Rugged aluminium housing with an internal shock-absorption design

Choose between two packages. No GPS contains the flight controller and the 2-14S power module — pair it with a compatible GPS/compass unit of your own for autonomous waypoint missions and precise position hold. M9N GPS adds SIYI's M9N GNSS module, so the autopilot is ready for position hold and waypoint flight out of the box. In both packages, the included power module lets you monitor battery voltage and current directly in your ground station.
