20DB Wireless Serial Port Transceiver Module RF 2.4G PA IPEX Antenna UART TTL RS232 for Ardiuno

2x 20DB Wireless Serial Port Transceiver Module RF 2.4G PA IPEX Antenna UART TTL RS232 for Arduino Raspberry pi



Overview:
TB387 is based on 2.4GHz frequency band wireless transparent data-transmission module.
Module supports most basic AT commands: baud rate, ID number, frequency settings and inquiries; factory settings; version information.
When the module is in AT module, users can use serial-port to issue AT commands to set the module's parameters.
When the module is in transparent data transfer mode, the user transmit data, frame number data module, add packaged rowcount, and then automatically transmit , at reliable range, the module will automatically re-transmit data to ensure successful transmission.
