Comidox 2Pcs 433Mhz HC-12 SI4463 Wireless Serial Port Module 1000m Replace Bluetooth

Product Features: Size?27.8×14.4×4mm The HC-12 module has three serial port transparent transmission modes, which are represented by FU1, FU2 and FU3. When using, all modes are only able to send and receive serial port data, no need to manage the wireless transmission part in the air. The system works in FU3 full-speed mode by default. FU1: This mode is a more power-saving mode, in which the module's idle operating current is about 3. 6mA. In this mode, the module can also set the 8 serial port baud rates as shown in the table below, but the air baud rate is unified to 250,000 bps. FU2: This mode is the power saving mode, in which the module's idle operating current is about 80?A. In this mode, the module only supports the serial port baud rate of 1200 bps, 2400 bps and 4800 bps, and the air baud rate is unified to 250,000 bps. Set to other serial port baud rate, the module can not communicate normally. At the same time, when set to FU2 mode in FU1 and FU3 modes, the serial port baud rate exceeding 4800 bps will be automatically reduced to 4800 bps. (After detection, there is a little bug when transmitting data in this mode, and users are not recommended to use FU2 mode for the time being) FU3: The module works at full speed and the idle working current is about 16mA. In this mode, the module automatically adjusts the wireless transmission air baud rate according to the serial port baud rate.
