This module acts as a wireless data communication module and operates in 2.4GHz frequency band. Its a low cost and low distance transparent communication module which can be used to transfer UART data from one device to another. There is no complex protocol for the data input. Just simply send a serial data from 1 end and it will be available in the other end. Works in half-duplex mode.
To use more number of data modules at the same place without data collision there is a option to choose the working channel using smd jumpers (ch) where it changes the operating frequency thus avoiding data collision.
No need to send CR (Carriage Return).
The compact size of 3.5cm x 1.5cm is suitable to make your existing device as wireless.
Operating Voltage : 5V
BaudRate : 9600
