Features:

The QA-210L is a serial port type 433 wireless transceiver kit with low power consumption, long distance and confidentiality. It includes a two-button remote control and a receiver module, which is especially suitable for receiving products requiring low power consumption.

 

Specifications:

Wireless frequency: 433.92MHz

Communication distance can reach more than 80 meters

Standby power consumption is less than 60uA

Wide working voltage: DC 3.3V~ 5V

 

Function Description:

 

This product is a low power serial data transparent transmission application. After the remote control presses the button, the receiving end directly reports the ID and button signal of the remote controller. The device side can perform code matching, function control and the like according to the data.

 

Serial communication protocol:

Serial communication baud rate: 9600bps

Serial port bit structure: 1+8+1, ie start bit + data bit + stop bit

Serial data format

Area	Header					ID		Data	CheckSum
Description	FC	00	0A	05	01	Remote control ID		Button data

Hearder: length 5Bytes, fixed to F5 00 0A 05 01

ID: 2Bytes in length, different remote controller IDs are inconsistent

Data: length 1Byte, the value of the button data is 1 or 2

CheckSum: 1Byte in length. Byte8 = BYTE0^BYTE1^BYTE2^BYTE3^BYTE4^BYTE5^BYTE6^BYTE7.

 

Precautions:

 

1. This module is a wireless communication electronic module. Please pay attention to moisture, drop and anti-static.

2. Pay attention to the power supply surge of the receiving module when applying, and avoid the power-on voltage higher than 5V.

3. When the module is shipped, the pin is installed by default. If it is not used for a long time, please pay attention to moisture, so as to avoid the moisture oxidation of the pin, affecting the pin contact effect and welding effect.
