HC-12 wireless RF UART communication module is another age of multi-channel implanted wireless information transmission module. The Radio frequency of 433.4 – 473.0MHz, can be setting a communication channel, step is 400kHz, a sum of 100 channels. The module most extreme send power is 100mW (20dBm), and – 116dBm collector affectability quality of the 5000bps baud rate, communication distance around 500 meters.
The module embraces a stepped hole encapsulation approach, which can be welded. The module size is 27.4mm*13.2mm *4mm (counting antenna seat, excluding the spring antenna), which is advantageous for the client to be installed in the application framework. The module has a PCB antenna seat ANT1, clients can utilize the coaxial link, the utilization of 433MHz band outer antenna.
The module additionally has antenna welding opening ANT2, advantageous client welded spring antenna. The client can pick one sort of antenna as indicated by the solicitation. The module contains MCU, clients don’t have to program moreover, simply send and get
UART information. The module utilizes an assortment of UART transmission mode, the client can pick
as indicated by the prerequisites of the utilization of AT order. The four UART methods of FU1, FU2, FU3, FU4, the normal working current is 3.6mA, 80μA, 16mA and 16mA, the greatest working current is 100mA (full power communicate state) HC12 Module depends on the SI4463 EZRadioPro family chip by SiLabs. This module offers a wireless information transmission and gathering scope of around 1 km in the outside. It’s a low power radio chip that is super simple to utilize.
This module has an installed STM8S003F3P6 MCU which is speaking with the SI4463 so the client can speak with the HC12 module utilizing a basic TTL 2 wire sequential interface (RX, TX, GND).
