N7 Autopilot Flight Controller: Genuine SIYI Hardware

This is a genuine SIYI module — the unit itself is clearly labeled “SIYI” alongside the “PX4” logo, and comes with SIYI’s own wide-range power module, supporting an unusually broad 2S-14S LiPo input in a single unit rather than requiring separate power modules for different voltage ranges. It’s built around SIYI’s own STM32H743 FMU running at up to 480MHz, paired with a separate STM32F103 IO co-processor, and backed by dual-redundant IMUs (BMI088 and ICM20689) plus internal shock-absorption for reliable flight data.

A few clarifications worth making precisely, checked directly against SIYI’s own published specifications: the magnetometer is an IST8310 (not RM3100 as sometimes listed), the barometer is a single MS5611 unit (not dual), and the PWM/IO output count is 13 total — 8 standard PWM plus 5 programmable I/O. None of this makes the board any less capable — it’s still a genuinely dual-IMU-redundant, PX4-and-ArduPilot-ready H7 autopilot — these are just the precise, manufacturer-confirmed numbers rather than rounder figures sometimes quoted elsewhere. This specific kit includes the flight controller and power module only; SIYI’s optional M9N GPS module is sold as a separate combo.
