iHaospace 2Pcs 433Mhz HC 12 SI4463 Wireless Serial Port Module 1000M Replace Bluetooth

The supply voltage is 3.2V~5.5V. (If the module is to be in the transmitting state for a long time, it is recommended to connect a 1N4007 diode in series when the power supply voltage exceeds 4.5V to avoid the built-in LDO heating of the module) The default communication distance (open field test): about 600m (the communication distance can be adjusted up to 1000m, the air baud rate is 5000bps). Default idle current: 16MA (module operating current is different in different operating modes). Operating frequency range (433.4-473.0MHz, up to 100 communication channels), maximum 100mW transmit power (settable) Default factory setting: working mode FU3, baud rate 9600bps, communication channel CH001 (433.4M).
