Highlights
- This is wireless serial transceiver module. And the frequency is 2.4GHz. There is the MCU on board with built-in encoding and decoding code and it is easy to implement remote control without pairing. You can set the ID number, working frequency and baud rate of the module through AT commands, and the modules who have the same ID number and operating frequency can communicate directly with each other. It is very popular for remote control systems, such as wireless doorbell, remote control rolling gates, smart car, smart home, etc.
