433Mhz HC-12 S14463 SI4438 Wireless Serial Port Module STM8S003F3U6 <br> <br>Power Supply Voltage : 3.2V~5. 5V.(if the modules working long hours in emission state, suggested that when the power supply voltage is greater than 4.5V you need concatenating a 1N4007 diode to avoid module built-in LDO got fever). <br>Default Communication Distance : about 600 m (communication distance is adjustable up to 1000 m, air baud rate 5000 BPS). <br>Default Idle Current: 16 mA (modules in different working mode of different current). <br>Default Working Mode :FU3, baud rate 9600bps, communication channel CHO01(433.4MHz) <br>Operating Frequency Range (433.4-473.0 MHz, as many as 100 communication channel) maximum 100 mw fired power (can be set) <br>Module supporting software upgrades. <br> <br>The HC-12 module has four serial port modes, which are represented by FU1, FU2, FU3 and FU4 under idle state is 3.6mA, 80uA, 1 6mA and 16mA respectively, and the maximum working current is 100mA(under full power emission state). <br>FU1 mode is a more power-saving mode, the idle working current of the module is about 3.6mA. In this mode, the module can also set the 8 serial port baud rates as shown in the

• HC-12 Power Supply Voltage: 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).
• 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: 16 mA (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).
