It's a relay board controlled by a nodemcu on board.
To control the watering of 3 zones and a pump to draw h2o from the rain barrels. It could be used for any other purpose where a max of 4 relays are involved and an i2c LCD screen for output is needed. Theres an i2c header on board.
Theres software included which is used to control the 3 zones (or 4 if you omit the pump) which uses svg graphics to control the zones. It works with touch zones.
