Click2Contact

The MultiConnect mDot is a secure, programmable, long-range and low-power RF module that provides data connectivity to sensors, industrial equipment and remote appliances. By employing Semtech long-range spread spectrum technology, bidirectional data communication can be maintained over 16 km suburban (2-5 km dense urban), deep into buildings and within noisy environments using the unlicensed ISM bands in North America, Europe and worldwide.

The module includes an integrated ARM Cortex-M4 processor and mbed-compatible software library for developers to control, monitor and bring intelligence to their IoT applications. It features ultralow power of around 28 mA @ 13 dBm, Rx of 10 mA and sleep mode of 0.1 µA. The product can run for years on batteries.

Interfaces include UART, SPI, I²C, 6 x DIO and 2 x analog, plus transparent interfaces for RS232 and RS485 cable replacement applications. Other features include 100 MHz clock speed; 512 KB Flash; 128 KB RAM; 860-1020 MHz frequency; adaptive data rates (300 bps to 300 Kbps); and AT-style control command.
