Second, product characteristics:

Super-regenerative receiver module using LC oscillator circuit, including amplification shaping, the output data signal with the decoded high-level signal, extremely easy to use, and inexpensive, it is widely used. With four decoded outputs (also can be changed to six-way jog or interlock 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, factory general emphasis on the 315MHz or 433.92MHz (if any special requirements adjustable frequency, frequency adjustment range is 266MHz ~ 433MHz. ). Receiver module generally use DC5V power supply, adjustable voltage range of any special requirements.
Third, the pin and use:
Pin Name Function Description
1 GND power supply negative (this position can be vacated without)
2 5V power supply positive
3 A (D0) Data output
4 B (D1) Data output
5 C (D2) Data output
6 D (D3) Data output
7 J (VT) Output status indication
8 - (GND) power supply negative
9-antenna terminal
A total of nine receiver module external interface, expressed above in English. "-" Indicates negative one, "+5 V" indicates positive power supply, "A, B, C, D" represents the output, "J" indicates that the output status indication.
Before use to connect 50 ohm 1/4 wavelength antenna and the antenna should be straight, in order to achieve the best reception, wavelength = speed of light / frequency.

Fourth, the application environment (applications)
Wireless remote control switch, remote control LED, alarm, 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.
V. Optional accessories
And the company launched series, supporting the use of remote control products.
Six, notes
VCC voltage is consistent with the operating voltage of the module, and the power to do the filtering;
Reception antenna great effect module, then the best 1/4 wavelength antenna, generally 50 ohm single-core wire, the length of the antenna is about 315M 23cm, 433M of about 17cm;
Antenna position also affected the reception of the module, install the antenna stretched as far as possible, away from the shield, high pressure, and the sources of interference;
Frequency used to receive, decode and transmit mode should match.
