HC-12 433 SI4463 Wireless Serial Module

The HC-12 is a long-range, 433MHz wireless serial communication module based on the Si4463 transceiver chip from Silicon Labs. It provides transparent UART communication over distances up to 1 kilometer (with line-of-sight) and is ideal for Arduino, microcontroller, and embedded system applications requiring reliable, low-power wireless data transmission.

With support for multiple baud rates, communication modes, and channels, the HC-12 offers great flexibility for use in remote sensing, telemetry, wireless control systems, and industrial automation. Its small form factor, built-in error correction, and configurable parameters via AT commands make it a powerful drop-in replacement for wired serial connections.

Frequency: 433 MHz ISM band Chipset: Silicon Labs SI4463 Data Rate: Up to 115200 baud serial communication Range: Up to 1 km (line of sight) Interface: UART serial Power Supply: 3.2V to 5.5V Use: Wireless serial data transmission, remote sensors, IoT communication
