Hc-12 433mh

HC-12 433Mh SI4463 Wireless Serial Port Module 1000m Replace Bluetooth HC12

• Supply voltage is 3.2 V ~ 5.5 V. (if the module has been in the transmitting state for a long time, it is recommended to connect a 1N4007 diode in series when the supply voltage exceeds 4.5 V to avoid the built-in LDO heating of the module.)

• Long distance communication. the standard communication distance (open field test) about 600m (the communication distance can be adjusted up to 1000m, the air baud rate is 5000bps).

• Frequency range433.4-473.0MHz.Transmit powermax: 20dBm

• Standard quiescent current: 16MA (module operating current is different in different modes).

• Factory default setting: working mode FU3, baud rate 9600bps, communication channel CH001 (433.4 M).

HC-12 module has four UART transparent transmission mode: FU1, FU2, FU3, and FU4. When in use, different modes are just send and receive UART data can be without a transmission part, but only the same air baud rate can communicate with each other sky! The system default in FU3 full speed mode, this mode can be set automatically and according to the baud rate of serial baud rate, low baud rate communication distance.
