The heart of this receiver is the UHF RX module. Its data is decoded by Decoder IC. DIP switch is used to set the code of RF module. You can interface it with microcontroller by checking the code of TX then set the DIP Switch of Receiver the same as TX. The output of this receiver is a 4-bit digital data. If any switch at TX is pressed, the LED with the same bit position will light out. It means active at logic LOW. A matching 434MHz 4-Button Remote Control, UTX4/434, is available.
