Relay Control Breakout Board _MAKE_SENSOR_LINE SIM808 GSM Location App NoteThis 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
