Discover the HC-12 Long Range Wireless Communication Module, a versatile wireless serial communication module with a range of 433.4-473.0 MHz and up to 1 km transmission. Operating on the STM8S003F3 microcontroller and Si4463 transceiver, it ensures reliable communication with a power-packed 20 dBm transmitter and a high-sensitivity receiver at 5000 bps. With the option for an external antenna, these modules can extend communication range beyond 1 km. Ideal for various applications, the HC-12 offers robust coverage for home and industrial settings. Upgrade your wireless communication with this STM8S003F3-powered marvel.

Features :

  • Frequency Range : 433.4 MHz to 473.0 MHz
  • Transmission Power : 20 dBm (100 mW)
  • Receiver Sensitivity : -117 dBm at 5000 bps
  • Communication Distance : Up to 1 km (in open areas)
  • Data Rate : Configurable, typically up to 9600 bps
  • Antenna Connector : Standard spring antenna included; external antenna can be added for extended range
  • Microcontroller : Built around the STM8S003F3 microcontroller
  • Transceiver : Utilizes the Si4463 transceiver
  • Operating Mode : Half-duplex

Specifications :

  • Working Voltage : 3.2V to 5.5V DC
  • Working Current:
    • Transmitting: 43 mA
    • Receiving: 19 mA
    • Sleep Mode: 1.8 mA

Sample Code :


#include <SoftwareSerial.h>

hc12Serial(2, 3);  // RX, TX

void setup() {
  Serial.begin(9600);
  hc12Serial.begin(9600);
}

void loop() {
  // Send data from Arduino to the other HC-12 module
  hc12Serial.print("Hello, HC-12!");

  // Wait for a response from the other HC-12 module
  while (hc12Serial.available() > 0) {
    char receivedChar = hc12Serial.read();
    Serial.print(receivedChar);
  }

  delay(1000);  // Adjust as needed
}
