Originally intended to control the lights of an aquarium, this board takes two 3.3V inverted logic inputs and drives two relays for powering up to 1.5A loads (give or take). The board requires 10VDC to 40VDC power to power the relay logic. For more details, read my blog post about the hardware setup.
