315M Super regenerative wireless remote control module drive

1、315M Introduction to remote control module

315MHz Remote control is a set of super regenerative radio communication module and radio remote control receiver . It is generally used 2272-M4 Decoding chip , With signal stability 、 It's a long shot 、 Features of simple application .

315M The module integrates LC Oscillating circuit , Embedded amplification shaping , The output data signal is decoded into a high-level signal , With four channel decoding IO Output .

315M Super regenerative wireless remote control is widely used in remote control switch 、 The remote control 、 Remote control socket 、 remote control LED、 Remote control sound 、 Remote control electric door 、 Remote control garage door 、 Remote control telescopic door 、 Remote control rolling gate, etc .

The pin description of the receiving module is as follows ：

Receiving module D0~D3 The pin corresponds to the remote control ABCD A button , When the remote control button is pressed , Corresponding key output high level ; When the remote control button is released , The corresponding pin stops output .

Be careful ： About 315M Specific use of remote control module , Please follow the instructions provided by the manufacturer .
