HC12 SI4463 Wireless Serial Port Module 1000m with Spring Shaped Antenna 433.4473.0MHz

Features: Builtin program, no need to pay attention to serial protocol automatic networking. Support one to multiple interconnection and transparent transmission. The open environment transmission distance is 1KM. Operating frequency range (433.4473.0MHz, up to 100 communication channels) Maximum 100mW transmit power. The module supports onetoone, onetomany, manytoone, manytomany connections. Four transparent transmission modes to suit different applications. Builtin MCU, free of programming, communication with external devices via serial port. Not limited to the number of bytes sent in a single transmission (FU1FU3 mode). Default factory setting: working mode FU3, baud rate 9600bps, communication channel CH001 (433.4M). Specification: Voltage:3.2~5.5V(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 builtin LDO heating of the module.) Distance:600m(The maximum communication distance can be adjusted to 1000m and the air baud rate is 5000bps) Default Standby Current:16mA( The working current of the module is different in different working modes ) Size:27.8 * 14.4 * 4mm 1.09 * 0.57 * 0.16in Working Frequency:433.4~473.0MHz Maximum Transmission Wattage:100mW Package List: 1*Module 1*Spring Shaped Antenna Builtin program, no need to pay attention to serial protocol automatic networking.
