HC12 Long Range 1Km Serial Transceiver Module (Original)

Description:
433Mhz HC-12 SI4463 Wireless Serial Port Module which can be used as an transciever for up to an 1000m range (line of sight).
Default idle current: 16 ma. (Current varies depending on the operating modes)
Default factory Settings: working mode FU3, baud rate 9600 BPS, communication channel CH001 (433.4 M).
Default communication distance : about 600 m (communication distance is adjustable up to 1000 m, air baud rate 5000 BPS).
Operating frequency range (433.4-473.0 MHz, as many as 100 communication channel) maximum 100 mw Transmitting power (can be set).
Power supply voltage : 3.2 V — 5.5 V.(if the modules is working for long hours in the burst transmit mode, then suggested that if the power supply voltage is greater than 4.5 V, concatenating an 1N4007 diode will avoid module built-in LDO heating up).

Specification:
Size: 27.8*14.4*4mm.
Color: show as pictures.
Power supply voltage: 3.2 V — 5.5 V.
Note:
There might be a bit color distortions due to different computer resolutions.
There might be a slight error due to different hand measurement.
Package included:
1 * HC-12 SI4463 Module.
