LoRa1121F33-1G9：High-Power Wireless Communication Module

LoRa1121F33-1G9：High-Power Wireless Communication Module

LoRa1121F33-1G9 module is built on SEMTECH's LR1121 chip, an ultra-low power, long-range LoRa transceiver supporting Sub-GHz and satellite-connected S-band communication. The LoRa1121F33-1G9 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.
