Description:

The super-regenerative receiving module adopts LC oscillation circuit, which contains amplification and shaping, and the output data signal is decoded high level signal, which is very convenient to use and cheap, so it is widely used. With four-way decoding output, easy to use;
The receiving module has a wide receiving bandwidth, generally ±10MHz, which is generally adjusted at 315MHz or 433.92mhz when it is manufactured. Generally, the receiving module is powered by DC5V.

Leg 7 bits,respectively, VT, D3, D2, D1, D0, the +5 V, GND and ANT. VT is a valid signal high output pin Upon receiving a valid signal, the pin output high, may also drive the relay.

There are four buttons on the remote control, corresponding to the receiving board feet four data bits D0, D1, D2, D3. Press the button to transmit a signal, the corresponding data bit will output high.

Applicable to wireless remote control switch, remote control socket, data transmission, remote control toy, anti-theft alarm host, garage door, rolling gate, gate, telescopic door and other door control industry and its remote control audio field.
