Board power capacity
« on: June 20, 2017, 01:11:55 pm »
Looking at running four zones at one time. Each valve draws .35 initial/.23 hold amps. Is there a software limit on the amount of zones operated at one time? What is the max amps that can be drawn through the board?

The controller's firmware does not set any limit.  The only limitation is the power supply and the water pressure.
The power supply is rated at 1A.  The board circuit trace is rated at 2A.
