RF Decoder - PT2272 - 433 MHz Decodes variety of RF remote control transmitters at 433 Mhz which uses encoder chip like PT2260, PT2262, PT2264, HS2260, SC2262, SC2260 Sunrom Part# 1421 User's Manual Doc Version: 1 9-Apr-16 A quality product, proudly made in India by Electronics http://www.sunrom.com/m/1421 1421 RF Decoder - PT2272 - 433 MHz Table of Contents Introduction .................................................................................................................................... 3 Typical Application ......................................................................................................................... 3 Features .......................................................................................................................................... 3 Interfacing with Microcontroller .................................................................................................... 3 Specifications .................................................................................................................................. 4 Module Pin Details.......................................................................................................................... 4 Board Schematic ............................................................................................................................. 4 AddressJumper ............................................................................................................................... 5 Product Dimensions ....................................................................................................................... 6 Support ............................................................................................................................................7 Disclaimer ........................................................................................................................................7 Page 2/7 Doc Version: 1 9-Apr-16 http://www.sunrom.com/m/1421 1421 RF Decoder - PT2272 - 433 MHz Introduction The product is a combination of 433 MHz RF Receiver and decoder IC PT2272 which is a fixed address type decoder. Fixed address means the user at transmitter and receiver will set address pins high or low and only the matching address will respond, else it is ignored. Typical Application • • • • Remote control Security Systems Sensor Networks Data collection Features • • • • • • Simple & Easy to use LED indication for valid data All interfacing IO on header 4 bit data output Address pads on PCB Crystal Stable RF Receiver Interfacing with Microcontroller If you want to operate with microcontroller then it's very simple to connect.

The option of address is to provide some security when multiple units are operated in same premises. Default we provide with all pins floating. If you want you can short that address pin to either high or low to set a unique address.
