"3-Way" features a 250 watt SPDT relay connected to GPIO 12 OUT.

GPIO 4 and 5 are pulled-up inputs intended for soft/hardware switches.


"2x2" is intended to replace a RainBird.

GPIO 4 and 5 out drive 24V@1 amp 2N2222 for relays, coils, solenoids, valves...

GPIO 12 and 13 are GPIO inputs for general purpose needs.


"Allie" features a 277vac/16amp relay connected to GPIO 12 for BIG power switching!

Also features (4) GPIO inputs connectorized to RJ45 for easy connectivity.


"BlindBird" is designed to WiFi control curtains/blinds/windows/electric doors & gates

Features TIP120 power transistor to drive motors up to 24v/3 amps,

and Forward/Reverse relay, plus 2 inputs intended for limit switches
