Two, product features:
The super regenerative receiver module uses the LC oscillation circuit, amplifying and shaping it, data signal output to the TTL level, can be directly to the decoder, is extremely easy to use, and the price is low, so it is widely used. The product has the advantages of small volume, high sensitivity; frequency point easy debugging, short delivery cycle; the quality of the products with good consistency, high ratio of performance to price, it is a kind of high frequency wireless remote control market was the largest and most widely receiving module. The receiving module receives wide bandwidth, generally for ± 10MHz, factory general tone in the 315MHz or 433.92MHZ (if there are special requirements can adjust the frequency, the frequency adjustment range is 266MHz~433MHz.). The receiving module using DC5V power supply, if there are special requirements can adjust the voltage, voltage adjustment range is 3~8V.
The quiescent current receiving module factory is generally 4mA, if there are special requirements can reduce the current, the minimum current can be adjusted to 1.5mA, but the receiving sensitivity will be reduced. The output module factory for noise output, if there are special requirements can be changed without noise output, but the receiving sensitivity will be reduced.
Three, the map dimensions (mm):  pls check enclosed picture
Four, pin and instructions:
Pin name function
The 1 ANT antenna terminal
2 VCC positive power supply
3, 4 DATA data output
5 GND negative
Receiving module, a total of four external interface, there are English said. "VCC" means the positive pole of a power supply, "DATA" said output, "GND" with the negative electrode of the power.
Antenna connected to 50 ohm 1/4 wavelength before use, and the antenna should be straight, in order to achieve the best reception, wavelength = speed / frequency.
Five, the application environment
Wireless remote control switch, remote control socket, data transmission, remote control toys, alarm etc..
Six, optional accessories
And the company launched series, supporting the use of remote control products.
Seven, note
The VCC voltage and working voltage module, and to do a good job of power supply filter;
Great influence on reception antenna module connected with the 1/4, the best wavelength antenna, generally use 50 ohm single core wire, the length of the antenna 315M is about 23cm, 433M is about 17cm;
The position of the antenna are also affected, the module receives the effect when installed, antenna as far as possible unbend, away from the shield, high pressure, local and interference source; receiving frequency, decoding method used and the oscillation resistance and emission matching
