Gravity Digital Wireless Receive Switch 433MHz Receiver

The Gravity wireless receiver from DFRobot receives 433 MHz signals in EV1527 format and outputs them on four digital outputs D0 to D3, which are LOW at rest and become HIGH when a signal is received. Counterparts are the Gravity wireless transmitter with four inputs and the battery-free wireless switch. Transmitters are paired and the operating mode is selected with the button on the board. In offices the connection reaches about 15 m according to DFRobot.

Note: The connection cable can be converted to male pins with a Dupont cable M-M, so that it also fits an Arduino UNO.
