LoRa1121:FCC ID & CE-RED Certified Sub-GHz and 2.4GHz dual-band communication module

LoRa1121:FCC ID & CE-RED Certified Sub-GHz and 2.4GHz dual-band communication module

The LoRa1121 module utilizes SEMTECH's LR1121 chip, an ultra-low-power, long-range transceiver that supports both global ISM band and 2.4GHz communication. The LoRa1121 supports LoRa and (G)FSK modulation in the Sub-GHz and 2.4GHz bands, as well as Sigfox® modulation in the Sub-GHz band, and long-range frequency hopping spread spectrum (LR-FHSS) in the Sub-GHz, 1.9-2.1GHz, and 2.4GHz ISM bands. The LR1121 complies with the physical layer requirements of the LoRaWAN® specifications released by the LoRa Alliance®, while remaining highly configurable to meet the needs of various applications and proprietary protocols.

LoRa1121 is produced and tested strictly using lead-free processes, and comply with RoHS and REACH standards,LoRa1121 has obtained FCC and CE Certified.
