I’m working on a basic smart watering system. I use Xiao ESP32-C3 with basic Grove Shield. I have already integrated moisture sensor, and now I need to add ability to turn on the 5V liquid pump. I have Grove Relay module, and I’m wondering if i am possible to provide only one source of power, that will work for both the pump and ESP32?
I would really appreciate your help, since I don’t want to fry ESP32.
