Average rating:

Works great so far. I wish in further versions you can set different mode for each channel and can setup a delay timer on each channel so it automatically turns off after a few seconds

This product is easy to use. Supply a +12V DC to + and tie the - to ground. Push learning button on the board once and push any key on remote will pair quickly. I had mine paired within 1 min from opening the box. Push A button on remote will activate Relay One at lower right hand corner close to the LED side. B button controls Relay 2 and so on. Once Relay is activated the B terminal is switched from the NC(normal Close) connection of C terminal to NO (Normal open) A terminal. I use this for my tennis ball machine which is a +12V battery powered machine. Note that the operating current is around 7mA when no relay is activated. Activating one relay will make the current go up to around 50mA, two to 100mA, three to 150mA and all four will be 200mA. So, for battery powered application and turn ON relay for long time, replace Relay with P-ch MOSFET probably is a better option.
