      Re: TTGO T-Higrow

      Hi all,

      I'm using T-Higrow and I have the water pump, I would like know if is posible to use the 5V pin from esp32 in order to run the water pump or maybe I have to connect the water pump to a external power source.

      Thanks

        @jcorbella You will need:

        1. a separate power supply rated for the pump
        2. a small relay or mosfet to switch the pump to help isolate the pump motor from the ESP32 circuitry
        3. all grounds connected to a "common"
        4. no power interconnections, I.e. power isolated between LilyGO and pump power supply
