HC-12 433MHz Long-Range Serial Module
—The HC-12 is a 433MHz wireless serial module that carries a transparent serial link up to a kilometre, with no pairing or network configuration.
Specifications
- 433MHz SI4463 transceiver
- Range up to roughly 1000m in the open
- Transparent serial — send bytes in, get bytes out
- 100 channels
- 3.2-5.5V supply
- Configurable power and baud rate by AT commands
What you can build with the HC-12 433MHz Long-Range Serial Module
- Long-range links between two boards
- Remote sensor readings across a farm
- Gate and pump control at distance
- Telemetry where Wi-Fi does not reach
Compatibility
Works with Arduino, ESP32, Pico and Raspberry Pi over serial. Note the band: 433MHz is licence-free in New Zealand under general user radio conditions with power limits, but for long-range mesh work LoRa on 915MHz is the better-supported choice.
Shipping
Dispatched from New Zealand with courier delivery nationwide, including rural addresses. Prices are in New Zealand dollars.
