 The main board requires DC power (7.5V .. 9V). The onboard 7805 regulator gives us the power for the micro and the relays. A 3.3V regulator keeps the ethernet module happy. The use of four-way DuPont female to female cables for hooking up the relay & ethernet module allows flexibility when mounting these parts in an enclosure. A red LED indicates that the unit is powered. A reset button is provided.
-The relay board has a couple of opto-isolated relays. Each rated at 10A for 250V. Be sure to [[http://www.elektor.com/subs/construction-electrical-safety.83362.lynkx|take care]] when working with any high voltages.
