HC-12 Wirless Transceiver Module (1KM)

  • HC-12 wireless RF UART communication module is a new generation of multi channel
    embedded wireless data transmission module.
  • Radio frequency of 433.4 – 473.0MHz, can be setting communication channel, step is 400kHz, a total of 100 channel.
  • The module maximum transmit power is 100mW (20dBm), and -116dBm receiver sensitivity air of the 5000bps baud rate, communication distance about 500 meters.
    The module adopts a stamp hole encapsulation method, which can be welded.
  • The module
  • size is 27.4mm*13.2mm *4mm (including antenna seat, not including the spring antenna), which is convenient for the customer to be embedded in the application system.
  • The module has a PCB antenna seat ANT1, users can use the coaxial cable, the use of 433MHz band external antenna.
  • The module also has antenna welding hole ANT2, convenient user welded spring antenna.
  • The user can choose one kind of antenna according to the request.
  • The module contains MCU, users do not need to program in addition, just send and receive UART data.
  • The module uses a variety of UART transmission mode, the user can choose
    according to the requirements of the use of AT command.
  • The four UART modes of FU1, FU2, FU3, FU4, the average operating current is 3.6mA, 80μA, 16mA and 16mA, the maximum operating current is 100mA (full power transmit state).
  • The HC-12 is a 100mW multi-channel wireless transceiver you can use in your projects to transmit and receive serial information.
  • The HC-12 is a half-duplex wireless serial communication module with 100 channels in the 433.4-473.0 MHz range that is capable of transmitting up to 1 km.
  • This project will begin by using the HC-12 to create a wireless link between two computers and end with a second article that creates a simple wireless GPS tracker.
