S3-A Custom APM Firmware Avionics System
Product Features
The S3-A avionics system features comprehensive upgrades in software-hardware
design and performance. It adopts a customized version of the open-source APM
firmware to deliver richer software functions. Also, it is equipped with the
high-performance STM32H7 series main control chip as its core, delivering powerful
computing support for unmanned device control. Its built-in IMU uses the BMI088
sensor with well-tuned shock-absorbing optimization design, enabling stable and
efficient attitude data acquisition even in complex environments, which greatly
improves the accuracy and reliability of the S3-A. In addition, screw-mounting holes
are specially added to the avionics system housing. This not only simplifies the
installation process but also guarantees assembly stability, building a solid
safeguard for the safe operation of unmanned devices.
