2.4G Wireless Serial Transparent Transceiver Module
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. - Working voltage: 3.2~5.2VDC - Working Current: 20mA(MAX) - Working Frequency: 2441MHz (the default)£¬ 2402MHz - 2529MHz programmable - Transmission distance: 30 meters (open area) - Logic Interface Type: UART TTL serial port - Communication format: 8N1 - Serial port baud rate: 9600 (default)£¬ can be modified to other values by command - Operating mode: When CMD pin is low£¬ it is AT command mode and it can be used to set the parameters of the module; When CMD is high£¬ it is transparent mode£¬ and it can communicate with the other one which has the same ID number and working frequency. - Antenna: Built-in PCB antenna - Great for DIY
