DESCRIPTION

HC-12 wireless serial communication module is a new-generation multichannel embedded wireless data transmission module. Its wireless working frequency band is 433.4-473.0MHz, multiple channels can be set, with the stepping of 400 KHz, and there are 100 channels in total. The maximum transmitting power of the module is 100mW (20dBm), the receiving sensitivity is -117dBm at a baud rate of 5,000bps in the air, and the communication distance is 1,000m in open space.

There is a PCB antenna connector (uFL) ANT1 on the module, and you can use an external antenna of 433M frequency band through coaxial cable; there's also an antenna solder pad ANT2 on the module to solder the spring antenna onto. You can choose what type of antenna you want to use.

There is a MCU inside the module, and you don’t need to program the module separately. The module adopts multiple serial port transparent transmission modes, and you can select them with an AT command according to usage requirements. The average working current of the three modes FU1, FU2 and FU3 in idle state is 80μa, 3.6mA an 16mA respectively. The maximum working current is 100mA (in transmitting state).

Notes

  • HC-11 cannot communicate with the HC-12, they work independently, in pairs.
