Pins and Instructions for Use

Pins (from left to right) and instructions for use:

Pin name and function description

1 DATA data input pin

2 VCC power positive pole

3 GND power negative pole

There are three external interfaces in the transmitter module, which are indicated in English. "VCC" means the positive pole of the power supply, "DATA" means the input, and "GND" means the negative pole of the power supply.

Receiver Specifications

• Actual Working Distance: 50 m to 100 m
• Supply Voltage: 5 VDC
• Working Current: 4 mA
• Operating Temperature Range: -10° C to +70° C
• Sensitivity: -105 DB
• Operating Frequency: 433.92 MHz
• Dimensions: 30 x 14 x 7 mm

Receiver Features

The super regenerative receiver module uses an LC oscillator circuit, which contains amplifying and shaping, and the output data signal is TTL level, which can be directly sent to the decoder, which is extremely convenient to use and low in price. 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).

Pin Position and Instructions for Use

Pin Name Function Description

1 ANT connected to the antenna terminal

2 VCC positive power supply

3, 4 RSD data output

5 GND negative power supply

The receiving module has a total of four external interfaces, which are indicated in English. "VCC" means the positive pole of the power supply, "DATA" means the output, and "GND" means the negative pole of the power supply.

Applications

Remote control switches, receiving modules, motorcycles, car anti-theft products, home anti-theft products, electric doors, rolling doors, windows, remote control sockets, remote control LEDs, remote control audio, remote control electric doors, remote control garage doors, remote control retractable doors, remote control rolling shutters, panning Doors, remote control door openers, door closers and other door control systems, remote control curtains, alarm hosts, alarms, remote control motorcycles, remote control electric vehicles, remote control MP3, remote control lights, remote control cars, security and other civil and industrial supporting remote control fields.

Note: For those who require a long distance, a 1/4-wavelength antenna can be connected. Generally, a 50-ohm single-core wire is used. The length of the antenna is about 23cm for 315M, and about 17cm for 433M; the antenna position also has the effect of receiving the module. When installing, the antenna should be as straight as possible, away from the shield, high voltage, and interference source.
