Relay Control Breakout Board

This breakout board allows a low power logic level device running at 5V to operate a relay. The relay can switch up to 16A 250VAC or 16A 30VDC. This lets your low power microprocessor control big, power-hungry devices! To use the board you simply connect a constant 5V supply along with a signal connection. When the signal connection is taken high (over 2.1V) the relay and onboard LED indicator turn on. At this point, the relay which is normally open becomes a closed circuit. Caution: This breakout board can be used with mains electricity, however we don't recommend it and should only be undertaken by suitably professionally qualified people. Stick to battery-powered devices, robots and similar! Features
