ESP32 Relay Board
For another project, I needed relays to be able to switch a couple of pumps. This is where the ES32 boards caught my eye on AliExpress. They come completely ready to use and some even have a 240V power supply on board. CAUTION: Although the programming port on the boards is marked as 5V, the fact that my boards…
