Description
HC-12 wireless serial port 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 totally 100 channels.
The maximum transmitting power of module is 100mW (20dBm), the receiving sensitivity is 117dBm at baud rate of 5,000bps in the air, and the communication distance is 1,000m in
open space.
The module is encapsulated with stamp hole, can adopt patch welding, and its dimension is
27.8mm×14.4mm×4mm (including antenna cap, excluding spring antenna), so it is
very convenient for customers to go into application system. There is a PCB antenna pedestal
ANT1 on the module, and user can use external antenna of 433M frequency band through
coaxial cable; there is also an antenna solder eye ANT2 in the module, and it is convenient for
user to weld spring antenna. User could select one of these antennas according to use
requirements.
There is MCU inside the module, and user don’t need to program the module
separately, and all transparent transmission mode is only responsible for receiving and sending
serial port data, so it is convenient to use. The module adopts multiple serial port transparent
transmission modes, and user could select them by AT command according to use
requirements. The average working current of three modes FU1, FU2 and FU3 in idle state is
80μa, 3.6mA an 16mA respectively, and the maximum working current is 100mA (in
transmitting state).
