Description

This product is a complete RF transmitter and receiver kit, which can realize wireless data transmission, remote control and other functions. In the open area without interference, the maximum wireless transmission distance can reach 2 kilometers.

The kit has a simple structure and flexible application, and can be directly applied to the design and experimental development of various products.

The popular link is like this: MCU -> Encoder -> Transmitter ------ Receiver -> Decoder -> MCU.You can use this kit to build a system with other main control equipment, such as Arduino, XIAO, to implement applications such as wireless security alarms, remote control tools, and so on.

The following is the introduction of the transmitter and receiver respectively.

[Transmitter]

In the remote wireless transceiver kit, the model of high-power wireless transmission module is LXPCF20, and its working voltage is 3-9v (DC). It adopts OOK modulation mode, which has the advantages of fast modulation rate and long transmission rate.

OOK (on-off keying) is binary switching keying. The modulation principle is to control the passage of the carrier by controlling the opening and closing of the switching device through the binary sequence, so as to load the binary signal onto the carrier. It is a low-cost and most easily implemented modulation method, which is widely used in various occasions.

[Receiver]

In addition, the model of superheterodyne decoding wireless receiving module is RX012 v2.0.The receiver is an ISM band receiving module with superior performance. It adopts industrial RF wireless data transmission and receiving chip, which has high receiving sensitivity and strong anti-interference ability. PT2272 decoding high-level output is added in the rear, which has good stability and high security.

There are three working output modes: non locking, interlocking and self-locking. The functions are different according to the chip model used. The default shipment is M4 non locking function. 

The functions are as follows: 

function 1: non locking - the chip model used is PT2272-M4 

function 2: interlocking - the chip model used is PT2272-L4 

function 3: self locking - the chip model used is PT2272-T4

Application

• Automobile remote control door switch

• Remote control door opener

• Wireless security alarm

• Remote control curtain machine

• Wireless industrial controller

• Wireless data transmission

• Wireless remote control model 

• Wireless toys control
