Title: ESP32 + ( MCP23017 + 16 Relay ) + (MCP23017 + 16 button)
Post by: signalz on December 22, 2021, 12:45:06 AM

Hi All,

I've bought esp32-poe and im planning to control 16 Relays (lights) with 16 buttons and web interface.

To do this, since i need 32 i/o, i've bought 2x mcp23017 units.

Have you done any similar setup like this ? Are there anything should i concern about ?

Thanks
