2023 - Arduino Mega with buzzer and ethernet with POE
From Dec-2023
This project is literally taking the Arduino MEGA, and adding the Arduino ethernet shield with POE to it on a single PCB. Some added extra pins, and all is based on the older Wiznet W5500, but still.. not too complicated to do. In theory. Then the manufacturer messes up the component placement big time, then the ethernet plug is physically unstable, then the Wiznet chip gets roasted at the customer for unknown reasons… “one of those projects”, I guess.
