HC-12 SI4438/4463 wireless long range 433M wireless serial port module UART interface

Built-in program without having to pay attention to the automatic networking of the serial protocol. Supports one to multiple connections and a transparent transmission.
The transmission distance in the open environment is 1 km. Operating frequency range (433.4-473.0 MHz, up to 100 communication channels). Maximum transmission power of 100 mW. 
The module supports one-to-one, one-to-many, many-to-one, many-to-many connections. Four transparent transmission modes for different applications. Built-in MCU, free of programming, communication with external devices via serial interface. Not limited to the number of bytes sent in a single transmission (FU1/FU3 mode). 
Factory setting: working mode FU3, baud rate 9600bps, communication channel CH001 (433.4M)
Specification:
Voltage: 3.2 ~ 5.5 V (If you want the module to be in the transmitting state for a long time, it is recommended to switch a 1N4007 diode in series when the supply voltage exceeds 4.5 V to avoid the built-in LDO heating of the module.)
Distance: 600 m (the maximum communication distance can be adjusted to 1000 m and the aircraft rate is 5000 fps).
Standard standby current: 16mA (the working current of the module is different in different working mode)
Size: 27.8 x 14.4 x 4 mm/1.09 x 0.57 x 0.16 inches.
Operating frequency: 433.4 ~ 473.0 MHz
Maximum transmitting power: 100mW


Package contents:
1 x module.
1 x spring-shaped antenna.
