@ksprayberry That's a good suggestion, bit I should have mentioned that I may need to 'pwm' the output at 20-30Hz so a relay won't last long.

I want to use an M5 to switch a 12v DC solenoid valve. I was hoping the GoPlus2 which takes a 12v input, but only outputs the motor voltage at 5v.
Is there an 'off the shelf' solution?
