  • Licence-free ISM spectrum enables worldwide deployment
  • Pre-soldered header speeds up development board integration

Dual-Band LoRa Development Board

The LORDWORLD Core1121 HF is a development board built around the LR1121 transceiver. It targets engineers and makers prototyping IoT edge devices that must operate across Sub-GHz and 2.4 GHz ISM bands. The module arrives with a pre-soldered header and integrated antenna for immediate bench testing.

Build Integration And Compatibility

The board communicates with SX126X, SX127X, and SX128X series chips, preserving links to existing LoRa nodes while adding LR-FHSS capability. It requires a host controller and power supply suited to low-power radio operation. The dual-band design frees the developer from choosing a single regional band during early prototyping.

Sustained Operation Characteristics

LoRa Chirp Spread Spectrum and Frequency Hopping Spread Spectrum modulation share the same hardware, allowing the firmware to switch schemes when interference rises. The LR1121 transceiver is specified for higher power efficiency, which supports long-duration transmissions in industrial, agricultural, or satellite IoT scenarios without thermal throttling concerns.

Points forts

  • Dual-band operation covers Sub-GHz and 2.4 GHz ISM frequencies
  • Compatible with SX126X, SX127X and SX128X LoRa transceivers
  • LoRa CSS and LR-FHSS modulation for robust links

Questions sur cet article

How far can the LR1121 module reach when running continuously on the 850-930 MHz band?

The LR1121 transceiver supports both LoRa CSS and FHSS modulation across Sub-GHz and 2.4 GHz ISM bands, providing higher power efficiency and longer transmission distance than previous SX126X, SX127X, and SX128X series while maintaining compatibility.

What thermal or noise behaviour should I expect from the Core1121 board during all-day operation?

The development board uses high-quality components for stable communication performance, and the LR1121 transceiver is designed for low-power operation across dual frequency bands without active cooling requirements.

Which host interface does the Core1121 development board expose for connecting to a microcontroller?

The board comes with pre-soldered headers for direct connection to a host MCU, enabling communication with the LR1121 transceiver that supports LoRa, (G)FSK, and LR-FHSS modulation schemes across 850-930 MHz and 2.4 GHz bands.
