In stock


  • Serial UART, Can work directly with your Micro-controller or Arduino TX/RX 
  • Long-distance wireless transmission (1Km line of sight with baud rate 5,000 bps).
  • Easy to use.
  • Maximum 100mW (20dBm) transmitting power .
  • Default 9600 baud. Can operate at higher speed but with the expense of more error and shorter range. Baud rate/channel can be modified using specific AT command.
  • You can change the wireless module parameters (baud rate, channel, and power dBm) by AT command.
  • Three working modes, adapting to different application situations.
  • Built-in MCU, performing communication with external device through serial port.
  • The number of bytes transmitted unlimited to one time.
