LORDWORLD Core1121 HF Dual-Band LoRa Module 850-930MHz development board

SKU CH-VRTR-MS6JH

Dual-band LoRa development board covering 850–930 MHz and 2.4 GHz with LR1121 transceiver compatible with SX126X, SX127X and SX128X series

  • Dual-band 850-930 MHz and 2.4 GHz coverage for flexible deployment
  • Communicates with SX126X, SX127X and SX128X series for easy migration
  • LoRa CSS and FHSS modulation for robust links in noisy environments
  • Globally licence-free ISM bands simplify regulatory compliance
  • LR1121 transceiver delivers higher power efficiency and longer range

Core1121 HF Dual-Band LoRa Module

The LORDWORLD Core1121 is a development board built around the LR1121 transceiver. It targets engineers and makers prototyping long-range wireless links in the 850-930 MHz range and at 2.4 GHz. The module supports LoRa, (G)FSK and LR-FHSS modulation schemes.

Suits multi-band ISM prototypes.

This board fits projects that need dual-band flexibility across Sub-GHz and 2.4 GHz ISM bands. It is less suitable for designs locked to a single legacy frequency or for ultra-low-power nodes that cannot accommodate a development-board form factor.

LR1121 transceiver with SX126X, SX127X.

The on-board LR1121 chip communicates with existing SX126X, SX127X and SX128X series devices, preserving investment in current LoRa infrastructure while adding CSS and FHSS spread-spectrum options. This compatibility is the key criterion when choosing this module.

Questions sur cet article

What host interface does the Core1121 development board need to connect to my controller?

The board exposes the LR1121 transceiver pins for SPI communication, so your host MCU must provide an SPI bus and the matching voltage level.

Will the Core1121 module talk to my existing SX126X, SX127X or SX128X nodes?

Yes, the LR1121 transceiver is compatible with SX126X, SX127X and SX128X series devices, allowing mixed networks after a firmware upgrade.

How can I confirm the Core1121 is transmitting on the 850-930MHz band after setup?

Use a spectrum analyser or a second LoRa node tuned to 850-930MHz to verify packets are received at the expected frequency and modulation.
