Description
A handy way to switch high current loads with nothing more than a 5 volt pilot signal from your Raspberry Pi or Arduino. The relays are driven through an optocoupler, so they can be connected directly to a 5V TTL signal from a micro controller. Just provide 5V and a Ground to the DuPont header as well as the signal lines. The relays are rated for up to 10A of current. Not suitable for 50 Volts and above.
