Last year we had a gameshow at my school with about 400 people watching. Ive built a buzzer system for it, consisting of 4 esp32 and a raspberry pi as the host. When a buzzer was pressed, it triggered a UDP message in the network for the raspberry pi, that locked all of the other buttons and sent a osc command to the grandma, led wall and triggered a sound effect. Because of the short time window I used a dev board and a w5500 breakout board, so that I could solder all of it easily together. It was on a messy perfboard. Because of that, troubleshooting was really time consuming.I started with looking for schematics for the breakout board, but didn’t find the exact ones, so im using the one from soldered a a guide. I now have the main chip wired up, but still need to do stuff like headers, power management and ethernet connection. After that I want to put an esp chip on there, so that it is all completely on the PCB.
