This module is based on 2-Coil Latching Relay. Contrast to the ordinary relay, this latching relay do not need continuous power to keep the state, only a rising/falling pulse is needed to change the work state. Even the power can be removed when the work state do not need to change, making this module especially suitable for low-power projects.
