#13016: HC-12 SI4463 Wireless Serial Module (433 Mhz 1000M Range)


This module is a versatile and popular choice for wireless communication projects, especially in scenarios where you need longer-range communication.

The HC-12 is a wireless transceiver module that operates in the 433MHz ISM (Industrial, Scientific, and Medical) band. It is known for its ease of use and versatility in wireless communication projects. Here are some key features and details about the HC-12 module:

1. Frequency Range: The HC-12 module operates in the 433MHz frequency range, specifically from 433.4MHz to 473.0MHz. This range is popular for long-range communication and is well-suited for various applications.

2. Communication Range: The module's communication range can vary depending on factors such as antenna quality, power supply voltage, and interference. In open field conditions, it can achieve a range of up to 1000 meters when properly configured.

3. Adjustable Baud Rate: The HC-12 module supports adjustable baud rates, typically ranging from 1200bps to 115200bps. You can choose a baud rate that suits your specific application requirements.

4. Multiple Communication Channels: It offers up to 100 communication channels, allowing you to set different modules to different channels to avoid interference when multiple modules are used in the same vicinity.

5. Low Power Consumption: The HC-12 module is designed for low power consumption, making it suitable for battery-powered applications. However, the power consumption may vary depending on the operating mode and transmission power.

6. Built-in Error Correction: The module includes error correction mechanisms to improve the reliability of data transmission.

7. Configuration Modes: The HC-12 module has different configuration modes, including a transparent mode and a command mode. In transparent mode, it acts as a wireless UART (Universal Asynchronous Receiver-Transmitter), allowing you to send and receive serial data wirelessly. In command mode, you can configure various settings using AT commands.

8. Firmware Updates: Some versions of the HC-12 module support firmware updates, enabling you to keep the module up to date with the latest features and improvements.

9. Compact Size: The module is relatively small, making it easy to integrate into various projects and devices.

10. Range Extender Mode: The HC-12 can be configured to operate as a range extender, allowing you to extend the communication range even further by using multiple modules in a relay fashion.

11. Applications: The HC-12 module is used in a wide range of applications, including remote control systems, telemetry, sensor data transmission, home automation, and any application where wireless communication is needed.

12. Arduino Compatibility: Many electronics enthusiasts and developers use the HC-12 module in conjunction with Arduino microcontrollers to create wireless projects.


It's important to note that while the HC-12 offers great flexibility and range for wireless communication, regulatory considerations and interference from other devices operating in the same frequency band should be taken into account when using this module in different regions. Always ensure that you are in compliance with local regulations regarding radio frequency use.



The HC-12 SI4463 module is commonly used in remote control, telemetry, wireless data acquisition, and other applications where reliable wireless communication is essential. If you have any specific questions or if there's anything else you'd like to know about this module or its applications, feel free to ask.

Product Details

  • Supply Voltage: The module operates within a supply voltage range of 3.2V to 5.5V. However, if you plan to use the module for extended periods in the transmitting state, it's recommended to include a 1N4007 diode when the supply voltage exceeds 4.5V. This diode helps prevent the module's built-in LDO (Low Drop-Out) regulator from overheating.

  • Communication Range: In open field conditions, the default address range of the module is about 600 meters. However, it's adjustable, and you can achieve a maximum communication distance of up to 1000 meters when configured properly. The communication baud rate is set to 5000bps.

  • Idle Current: The module consumes approximately 16mA of current when idle. Keep in mind that power consumption may vary depending on the specific operating mode.

  • Dimensions: The module has compact dimensions, measuring 27.8 x 14.4 x 4mm. This small size makes it suitable for various applications with limited space.

  • Operating Frequency Range: The module operates in the frequency range of 433.4MHz to 473.0MHz. This range provides flexibility for communication in various regions and environments. It offers up to 100 channels for communication.

  • Transmit Power: The module supports a maximum transmit power of 100mW, which can be set according to your requirements.

  • Software Upgrade: The module is capable of supporting software upgrades, allowing you to update its firmware if needed.

  • Default Factory Settings: The default factory settings include Mode FU3, a baud rate of 9600bps, and communication channel CH001 at 433.4MHz.
