HC-12 SI4463 Wireless Serial Port Module - 433MHz

With the HC-12 module you can send data between two devices at a great distance.
The module is equipped with an SI4463 Transceiver IC in combination with a STM8 microcontroller.
Communication via an Arduino is very easy via UART (RX and TX) signals.

Specifications:

• Voltage: 3.2V - 5.5V DC
• Power consumption (peak, maximum): <200mA
• Power consumption (continuous, maximum): <100mA
• Frequency range: 433.4-473MHz (adjustable in 100 separate channels)
• Built-in STM8 microcontroller for simple communication via RX and TX
• Distance (open air, maximum): 1000m (at 5000bps in open air*), 1800m (at 500 bps in open air in FU4 mode*)
• Transmission power: up to 100mW (adjustable)
• Receiver sensitivity (maximum): -117dBm (see datasheet)
• Baud rate adjustable from 1200 to 115200 (standard 9600)
• 433MHz antenna included (separate, not soldered)
• Possibility for antenna via the uFL/IPEX connector
• Temperature range:  -40°C to +85°C
• Dimensions: 27.4 x 13.2 x 2mm

* Only achievable in ideal conditions with directional antennas.

Note:According to the datasheet (page 3) it is recommended to put a 1N4007 diode (or similar) in series with the Vcc pin if the voltage is more than 4.5V.
