This is a 4 bit wireless module. Use it to transmit and receive 4 bits of wireless data through a wireless RF Link. It is our RF Modules and the HT12E/D IC. The transmitter and the receiver come with a 8 bit address selector switch which can be used to assign unique addresses to each wireless link. Receivers receive data only from transmitters which have a matching 8 bit address. The module can operate within a range of 100m when the transmitter is in line of sight and around 50m when indoors.
The transmitter and the receiver can be directly connected to a microcontroller or an external circuit through the header pins.
