A cost-effective fully integrated walkie talkie module with built-in high-performance RF transceiver chip, microcontroller and RF power amplifier (PA). The external controller sets the parameters and functions of the module through the standard asynchronous serial interface (RS232), and can control the sending and receiving of the whole module through the serial port at command.

The module has the advantages of small volume, high integration, stable performance, flexible application, and conforms to the interphone standards of most countries in the world. It is easy to pass CE / FCC certification; This module can be used to make a small walkie talkie, or the module can be embedded into other handheld terminal devices to realize the wireless walkie talkie function. Generally, some walkie talkie modules are mainly for users who need to increase the wireless walkie talkie function. Users do not need to understand the detailed walkie talkie technology to develop the software and hardware of the walkie talkie part, just according to the circuit interface provided by us, Data mode and communication object can be operated, which can save the user's technical investment cost, Shorten the time to market of its products.
