Introduction This product is a long-range, ultra-low-power transceiver that supports ISM sub GHz (150-960MHz), global 2.4GH z band, and 1.9 - 2.1GH z satellite band, suitable for terrestrial and satellite communication applications. It supports LoRa, (G) FSK, and LR-FHSS modulation methods, and can be used in LoRaWAN standard networks or private protocols to meet the needs of LPWAN applications. The LR1121 integrates a low-power multi-band RF front-end with extremely high frequency configuration flexibility. Features Based on the third-generation low-power LoRa transceiver LR1121 Supports Sub-GHz (150MHz ~ 960MHz), S-band ( 1.9GH z ~ 2.1GH z), and 2.4GH z ISM frequency bands Connects to the cloud via LoRa or LoRaWAN protocol through a gateway, enabling low-power wide-area networking (LPWAN) Supports LoRa, (G) FSK, and LR-FHSS modulation schemes, compatible with SX126X/SX127X series for easy product upgrades SPI communication interface, supports mainstream MCU platforms for seamless integration and migration Integrates AES-128 encryption engine to enhance data security Onboard TCXO crystal oscillator ensures frequency stability under extreme temperature conditions Suitable for IoT applications such as industrial telemetry, smart home, environmental monitoring, and remote data acquisition Comes with online development resources and manual (examples for ESP32 / Raspberry Pi / STM32 / Raspberry Pi Pico) Package Content Core1121-HF x1 IPEX4 to SMA cable x1 2DB SMA antenna x1 2.4G antenna x1 Note Development Resource is provided, please contact with us to get if needed.
