Introduction

The LoRa1121 is an ultra-low-power long-range LoRa transceiver module based on the SEMTECH LR1121 chip. The module supports Sub-GHz, global 2.4GHz ISM band, and S-band communications for satellite connectivity. It supports LoRa, (G)FSK modulation, Sigfox protocol, and LR-FHSS technology, and is compatible with the LoRaWAN communication protocol for use as a LoRaWAN node, while its flexible configuration capability accommodates diverse application requirements and proprietary protocols. The module is manufactured and tested using a lead-free process, complies with RoHS and REACH standards, and has obtained FCC and CE certifications.
