HC-12 433 SI4463 Wireless Serial Module Remote 1000M With Antenna

HC-12 433MHz SI4463 Wireless Serial Module Remote 1000M With Antenna is a high power, long range and easy to use RF wireless transceiver module based on the popular SI4463 IC. It works at the 433 MHz comes with an external spring antenna and can work in ranges upto 1000 meters (requires stable power supply, low datarate and low surrounding interference with line of sight). This is one the cheapest and easiest modules to do wireless communications using Arduino, Raspberry Pi and other micro controllers. Libraries and sample codes are available for Arduino and Raspberry Pi which will make it easier for you to start using the wireless module.

Use it to do bidirectional communication between devices. It has a standard Serial interface, which means you can directly interface this module to any microcontroller without the need for any external circuit.

This RF transceiver is perfect to making wireless robots, home automation, wireless transmission of audio and video, etc.

HC-12 wireless serial port communication module is a new-generation multichannel embedded wireless data transmission module. Its wireless working frequency band is 433.4-473.0MHz, multiple channels can be set, with the stepping of 400 KHz, and there are totally 100 channels. The maximum transmitting power of module is 100mW (20dBm), the receiving sensitivity is -117dBm at baud rate of 5,000bps in the air, and the communication distance is 1,000m in open space.

HC-12 is a long-distance wireless transmission with the range of 1,000m in open space/baud rate 5,000bps in the air.Working frequency range is 433.4-473.0MHz, up to 100 communication channels Maximum 100mW (20dBm) transmitting power (8 gears of power can be set) Built-in MCU, performing communication with external device through serial port. The number of bytes transmitted unlimited to one time.Update software version through serial port.

The HC-12 433 SI4463 Wireless Serial Module is designed with a stamp hole encapsulation, allowing for patch welding, and measures 27.8mm x 14.4mm x 4mm (including the antenna cap, excluding the spring antenna), making it highly convenient for integration into application systems. It features a PCB antenna pedestal ANT1, enabling the use of an external antenna for the 433M frequency band via a coaxial cable. Additionally, there’s an antenna solder eye ANT2 within the module, offering the convenience of welding a spring antenna. Users have the flexibility to choose between these antenna options based on their specific requirements.

Internally, the module houses an MCU, eliminating the need for separate programming by the user. The transparent transmission mode is straightforward, tasked solely with the reception and transmission of serial port data. Multiple serial port transparent transmission modes are available, selectable via AT commands to suit different user needs. The idle state current consumption for modes FU1, FU2, and FU3 averages at 80 uA, 3.6mA, and 16mA respectively, while the peak current during transmission reaches up to 100mA.

Specification:

• Supply voltage: 3.2V~5.5V. (If the module you want to work long hours in the emission state, it is recommended that when the supply voltage exceeds 4.5V threaded a 1N4007 diode to prevent module built-in LDO heated)
• Default address range (open field test): About 600m (maximum communication distance adjustable reach 1000m, the baud rate is 5000bps)
• Default idle current: 16MA (In different working modes operating current is different)
• Module dimensions: 27.8 x 14.4 x 4mm
• Operating frequency range: 433.4-473.0MHz, up to 100 channels of communication
• The maximum transmit power: 100mW (settable)
• Module support software upgrade
• Default factory settings: Mode FU3, baud rate is 9600bps, communication channels CH001 (433.4M)
