Product Name: 5V high frequency superheterodyne four channel decoding and receiving module

1, Technical parameters

Working voltage (V): DC5V

Static current (MA): 4.5mA

Modulation mode: amplitude modulation (ook)

Working temperature: - 10 ℃ ~ + 70 ℃

Working mode: M4 (inching: press and hold the output without releasing the hand, and stop the output after releasing the hand), L4 (interlock: four channels can only have one output at the same time), T4 (self-locking: four channels can output independently and have no influence on each other, press output once and then stop output again)

Size (LWH): 38.5 * 23.5 * 7mm

2, Product features:

Superheterodyne receiver module uses LC oscillation circuit, including amplification and shaping. The output data signal is high-level signal after decoding. It is very convenient to use and low-cost, so it is widely used. With 4-channel decoding output (can also be changed to 6-channel inching or interlocking output), easy to use; frequency debugging is easy, short supply cycle; good product quality consistency, high cost performance.

The receiving module has a wide receiving bandwidth, which is generally ± 10MHz, and is generally adjusted at 315MHz or 433.92mhz (if there are special requirements, the frequency can be adjusted from 266MHz to 433MHz). The receiving module generally adopts DC5V power supply, and the voltage range can be adjusted if there are special requirements.

3, Foot position and instructions:

The receiving module has eight external interfaces, which are expressed in English. "5V" refers to the positive pole of the power supply, "d0, D1, D2, D3" indicates the output, "GND" indicates the negative pole of the power supply, and "ant" indicates the antenna terminal.

A 50 ohm 1 / 4 wavelength antenna should be connected before use, and the antenna should be straight to achieve the best reception effect, wavelength = light speed / frequency.

4, Application environment (application field)

Wireless remote control switch, remote control socket, data transmission, remote control toys, anti-theft alarm host, garage door, rolling gate, gate, telescopic door and other door control industry and remote control audio field.

5, Optional accessories

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

6, Remarks

The VCC voltage should be consistent with the working voltage of the module, and the power filter should be done well;

The antenna has a great influence on the receiving effect of the module. It is better to connect a quarter wavelength antenna with a 50 ohm single core wire. The length of the antenna is about 23cm for 315m and 17cm for 433M;

When installing, the antenna should be as straight as possible, far away from the shield, high voltage and interference source;

The receiving frequency and decoding mode should match with the transmission 

Other styles of remote control modules;

 Notice:

1: The receiving module is fixed code receiving, and supports fixed code (welding address code) remote controller 

2: This module can only output high-level signal after receiving the remote controller with the same frequency and 8-bit address code to complete decoding.

3: If you only purchase receiving parts, you cannot use them. The receiver is part of the remote control

4: You can use a remote control with the same fixed code frequency to match this module, or you can buy a remote control from us. It's well matched.
