Product Name: 5 VDC high-frequency four super-regenerative receiver module ,

The technical parameters:

  • First, the working voltage (V): DC5V
  • Quiescent Current (mA): 4.5MA
  • Modulation: AM (OOK)
  • Working temperature : -10 ℃ ~ +70 ℃
  • Receiver sensitivity (dBm):-105DB
  • Operating Frequency (MHz): 315,433.92 MHz (266-433MHZ frequency band may be optionally )
    Encoding: Encoding pad ( fixed code )
  • Work : M4 ( Jog : Hold outputs let go , let go to stop output ), L4 ( interlock : four while only one output ), T4 ( self-locking : four independent outputs , and do not influence , click the output and then click stop output )
  • Size (LWH): 41 * 23 * 7mm

Product characteristics :
Super-regenerative receiver module using LC oscillator circuit , containing amplification shaping, the data signal output is high signal decoded , extremely easy to use and inexpensive, it is widely used. With four decoded outputs ( also can be changed to six-way jog or interlocking output ) , easy to use ; frequency debugging easy , short lead times ; product quality, consistency, and cost-effective.

Receiver module has a wide receiver bandwidth, typically ± 10MHz, 315MHz factory usually tune in or 433.92MHZ ( if any special requirements to adjust the frequency adjustment range , the frequency of 266MHz ~ 433MHz.). Receiver module generally use DC5V power supply, adjustable voltage range of any special requirements .

Pin and instructions :

  • 1 VT output status indication
  • 2 D3 data output
  • 3 D2 data output
  • 4 D1 data output
  • 5 D0 data output
  • 6 5V power supply positive
  • 7 GND power negative
  • 8 ANT antenna terminal connected

Receiving a total of eight external interface module , above the English said . "5V" indicates positive power supply , "D0, D1, D2, D3" represents the output , "GND" represents negative one , "ANT" means an antenna connection terminal .
Before use to connect a 50 ohm 1 / 4 wavelength antenna , and the antenna should be straight , in order to achieve the best reception, wavelength = speed of light / frequency .

The  application environment ( applications )
Wireless remote control switch , remote control socket , data transmission, remote control toys , burglar alarm host , garage doors, gates , road gates, retractable doors gated industry and its remote audio fields.

Optional accessories
With the company launch series , supporting the use of remote control products .

VCC voltage to be consistent with the module operating voltage, and power to do the filtering ;
Impact on the reception antenna module is large, then the best 1/ 4 wavelength antenna , generally use 50 ohm single wire antenna length 315M is about 23cm, 433M of about 17cm;
Also affect the position of the antenna reception module , install the antenna stretched as far as possible away from the shield , high pressure, and local sources of interference ;
When using the reception frequency , the transmitter should match decoding
