SIYI N7 Autopilot Flight Controller with GPS

The SIYI N7 Autopilot Flight Controller is a high-capability Pixhawk-style board built for serious UAV, UGV or USV builds using the ArduPilot or PX4 ecosystem. It’s ideal for large drones, VTOLs and multicopters where sensor redundancy, wide input voltage range and robust I/O are essential.

Key features

• Dual redundant IMUs (BMI088 + ICM20689) plus internal shock absorption and magnetic compass (IST8310) give high inertial reliability even in vibration-prone setups. ([rayiaero.com](https://www.rayiaero.com/Flight%20Control/siyi-n7-autopilot-flight-controller1.html?utm_source=openai))

• Powered via 2–14S battery through the included power module, with output regulated to ~5.2 V for the controller and continuous current handling up to 60 A (100 A peak for short bursts). ([siyi.biz](https://www.siyi.biz/en/product/autopilot-power/n7-power-module/spec/?utm_source=openai))

• Host MCU is STM32H743IIK6 (480 MHz, 2 MB flash /1 MB RAM) and secondary STM32F103 coprocessor for I/O tasks—enough headroom for demanding PX4 / ArduPilot workloads. ([rayiaero.com](https://www.rayiaero.com/Flight%20Control/siyi-n7-autopilot-flight-controller1.html?utm_source=openai))

• Rich interface set: 4 UARTs, 3 I2C, 1 CAN, USB-C, TF card slot, SBUS input, GPS and safety ports, 8 standard PWM outputs + 5 programmable I/O. ([rayiaero.com](https://www.rayiaero.com/Flight%20Control/siyi-n7-autopilot-flight-controller1.html?utm_source=openai))

• Complete environmental range: works from −20 °C to +65 °C; form factor 47×68×19 mm and weight 57 g, balancing ruggedness with manageable payload impact. ([rayiaero.com](https://www.rayiaero.com/Flight%20Control/siyi-n7-autopilot-flight-controller1.html?utm_source=openai))

Use the N7 Autopilot with its power module for full battery and current monitoring; ensure your battery is within the 2-14S range and that the XT60 connector is compatible. When using GPS (e.g. M9N or RTK/PPK), position it away from high-power or magnetic interference for reliable navigation. Its rich I/O makes it suitable for fully featured builds with cameras, telemetry, gimbals, airspeed sensors and safety switches.
