The MultiConnect® mDot™ Box/EVB is an ARM® mbed programmable Long Range RF LoRa end-point device that allows customers a fast and cost-effective means to validate LoRa IoT applications. The device features built-in sensors that display temperature, ambient light, pressure, elevation and accelerometer information. The device also contains a Multi Connect mDot. Two versions are available: 1) the Box that encloses the electronics in a plastic chassis and 2) the EVB that is a developer-board only. The Box also comes with GPS. The mDotBox removes the need for heavy configuration or embedded design skills, making it much easier and faster to evaluate and bring LoRa IoT applications to market. The mDotBox operates on the unlicensed spectrum wireless technology for the 915 MHz ISM band in the United States and Canada and 868 MHz in Europe.
