Main features of Siyi N7 flight control

• H7 double‑precision floating‑point unit processor
• High‑performance, low‑noise automotive‑grade IMU and magnetometer
• Dual‑redundancy hardware design
• Built‑in internal shock‑absorbing structure
• Compatibility with Ardupilot and PX4 ecosystems
• Turn‑key systematic solutions

The Siyi N7 flight control system works with a wide range of Siyi hardware products and open‑source ecosystem devices, easily satisfying diverse application requirements. Compatible with high‑performance firmware and software such as PX4, ArduPilot, QGroundControl and Mission Planner, this controller delivers robust system solutions for many practical use‑cases. Beyond that, the platform reduces development barriers for developers. Engineers can leverage its complete toolset to build custom applications.

IMU thermostatic control

The N7 flight controller adopts an internal shock‑absorbing mechanical structure. It fits different types of airframes. It implements built‑in dual IMU redundancy. Both the GPS‑module magnetometer and flight‑board magnetometer use dual‑redundant layouts. A built‑in heating resistor keeps the IMU running at stable temperatures in cold environments. This full‑stack system design greatly improves flight stability and operational reliability.

H7 double precision floating point unit processor

The N7 flight controller integrates the STM32H743IIK6 chip. This chip includes DSP and double‑precision FPU units. Its main frequency reaches up to 480 MHz. It carries 2 MB flash memory and 1 MB RAM. It delivers strong computing power and fast data processing. These capabilities notably enhance flight stability. They also create more room for extended feature development.

Optional RTK and PPK to meet high-precision application scenarios

Vehicle manufacturers and developers may add compatible RTK or PPK modules. They can achieve centimeter‑level positioning. This suits survey‑mapping, agricultural spraying and other high‑precision tasks. Siyi RTK and PPK perform well in complex magnetic‑field conditions. They support GPS direction‑finding functions. Users are less affected by compass magnetic interference.
