LoRa1121F33-2G4:2W High-Power Wireless Communication Module
LoRa1121F33-2G4 module is built on SEMTECH's LR1121 chip, an ultra-low power, long-range LoRa transceiver supporting Sub-GHz and 2.4G band. supports LoRa, (G)FSK modulation, Sigfox protocol, and LR-FHSS. It is compatible with the LoRaWAN communication protocol and can function as a LoRaWAN node. Additionally, it offers flexible configuration options to meet the requirements of various applications and proprietary protocols.
