Product parameters

1. Technical parameters
Working voltage (V): DC5V
Quiescent current (mA): 4.5MA
Modulation method: amplitude modulation (OOK)
Working temperature: -10℃~+70℃
Receiving sensitivity (dBm): -105DB
Working frequency (MHz): 315, 433.92MHz (266-433MHZ frequency range can be selected)
Coding method: pad coding (fixed code)
Working mode: M4 (jogging: output when pressing and not letting go, and stop output as soon as you let go), L4 (interlock: four channels can only have one output at the same time), T4 (self-locking: four independent outputs, no each other Affect, click output and then click to stop output)
Size (LWH): 40*20*7mm
2. Product Features:
The super-regenerative receiver module uses an LC oscillator circuit, which contains amplifying and shaping, and the output data signal is a decoded high-level signal, which is extremely convenient to use and low in price, so it is widely used. With four-channel decoding output (also can be changed to six-channel jog or interlock output), it is easy to use; frequency point debugging is easy, the delivery cycle is short; the product quality is consistent and the price is high.
The receiving module has a wide receiving bandwidth, generally ±10MHz, and is generally adjusted to 315MHz or 433.92MHz when leaving the factory (if there are special requirements, the frequency can be adjusted, and the frequency adjustment range is 266MHz~433MHz.). The receiving module generally uses DC5V power supply, and the voltage range can be adjusted if there are special requirements.
3. Pin position and instructions for use:

The receiving module has a total of nine external interfaces, which are indicated in English. "—" means the negative pole of the power supply, "+5V" means the positive pole of the power supply, "A, B, C, D" means output, and "J" means output status indication.
Before use, connect a 50 ohm 1/4 wavelength antenna, and the antenna should be straight to achieve the best reception effect, wavelength = speed of light / frequency.
4. Application environment (application area)
Wireless remote control switches, remote control LEDs, alarms, remote control sockets, data transmission, remote control toys, anti-theft alarm host, garage doors, rolling gates, road gates, retractable doors and other door control industries and remote control audio fields.
Five, optional accessories
Use with the company's launch series and remote control series products.
Six, remarks
The VCC voltage must be consistent with the module's working voltage, and the power supply must be filtered;
The antenna has a great influence on the receiving effect of the module. It is best to connect a 1/4-wavelength antenna. Generally, a 50-ohm single-core wire is used. The length of the antenna is about 23cm for 315M and 17cm for 433M;
The position of the antenna also affects the receiving effect of the module. When installing, the antenna should be as straight as possible, away from the shield, high voltage, and interference sources;
When in use, the receiving frequency and decoding method should match the transmission.

Notice:
1 This RF receiver module only supports remote controllers with fixed codes (2260/2264 chips)
2 This receiving module has an 8-bit pad address code that needs to be matched with the 8-bit pad address code of the remote control before it can communicate.
3 If you only purchase the receiving module, it cannot be used. It is a part of the remote control system and needs to be used with the remote fixed code remote control to achieve control.
4. You can use this kind of fixed code remote control with the same frequency for supporting use, or you can buy a receiver from us, the pairing is good.
