MATEKSYS AP Periph Adapter Node - CAN-G474

Description

The MATEKSYS CAN-G474 enhances drone communication with its high-speed 5 Mbit/s CAN transceiver and STM32G474 MCU, built on ArduPilot's AP_Periph firmware. It supports seamless integration of ArduPilot peripherals like GNSS, Compass, Barometer, and Rangefinders into DroneCAN systems, as well as GPIO-based devices such as PWM and LED notify modules, offering a simple solution for expanding drone functionality.
