Product Features :

The super-regenerative receiver module using the LC oscillator circuit containing amplifier shaping, the output data signal is decoded high signal, extremely easy to use and inexpensive, so widely used. With four decoder output (can be changed to six-way jog or interlock output), easy to use; frequency debugging easy, short lead times; consistency of product quality, cost-effective.

Receiver module has a wide receiver bandwidth, typically ± 10MHz, factory general tone in the 315MHz or 433.92MHZ (if there are special requirements for adjustable frequency, the frequency adjustment range is 266MHz to 433MHz.) The receiver module is generally DC5V power supply, and any special requirements to adjust the voltage range.

Pin and instructions for use:

Prior to use to connect the 50 ohm 1/4 wavelength antenna, and antenna should be straight in order to achieve the best reception, wavelength = speed of light / frequency.
