Overview
The Inventory Master LoRa transceiver module is a compact and user-friendly embedded radio modem operating in the 434 MHz ISM band. Leveraging LoRa® technology, it achieves extensive communication range with low power consumption, though at a bit lower rate. With exceptional sensitivity, it can penetrate previously challenging RF environments.
