MultiTech MultiConnect® mDot™ LoRa® Modules

MultiTech MultiConnect® mDot™ LoRa® Modules are designed to provide long-range, low-bit-rate M2M data connectivity to sensors, industrial equipment, and remote appliances. For ease of use, the low-power mDot Modules are pre-certified and Arm® Mbed™ programmable. The Modules are LoRaWAN® 1.0.2 compliant, providing bi-directional data communication up to 15km (10 miles) line-of-sight and 2km (1 to 3 miles) in buildings, using sub-GHz ISM bands in North America, Europe, Australia, and Asia Pacific (AS923). The mDot Modules bring security, intelligence, reduced complexity, and a low overall bill of material cost to the very edge of the network while supporting a variety of electronic interfaces to connect just about any device for years on battery power.

The MultiTech MultiConnect mDot Modules are available for a wide variety of regions (North America, Europe, Australia/New Zealand, Asia/Pacific, and Japan) and with several antenna input options (SMA, u.FL, RF pad).
