Project description

MAVLink Ethernet Bridge with WIZnet W5500 Project Overview In drones and autonomous robots, reliable communication is just as important as motor control. Data such as GPS position, speed, attitude, battery status, and mission information must be continuously exchanged between the vehicle and the Ground Control Station. This project uses a Raspberry Pi Pico and WIZnet W5500 to bridge MAVLink communication from a Flight Controller to Ethernet using UDP. The key idea is to extend UART-based communication into a standard IP network without making major changes to the existing Flight Controller…
