The MultiConnect mDot from Multi-Tech Systems is a secure, programmable,
long-range and low-power RF module that provides data connectivity to sensors,
industrial equipment and remote appliances.
The Semtech LoRa Long Range Spread Spectrum technology can be employed
to maintain bi-directional data communication over 16km, deep into buildings
and within noisy environments using the unlicensed ISM bands in North America,
Europe and worldwide.
The mDot RF module features an integrated ARM Cortex-M4 processor and
mbed compatible software library for developers to control, monitor and bring
edge intelligence to their Internet of Things (IoT) applications.
Key features of MultiConnect mDot RF modules include Cortex M4 STM32 MCU,
100MHz clock speed, 512KB Flash and 128KB RAM; frequency 860-1020MHz; ultra low
power around 28mA@13dBm; Rx 10mA; sleep mode 0.1uA; ultra long range operation,
2-5km typical in dense urban and 16km+ in suburban; link budget on 0dBi
antenna, 152dB point to multiple points; 147dB point to point; and adaptive
data rates (300bps to 300kbps).
The MultiConnect mDot is customer programmable via ARM mbed libraries
(400KB Flash available); and also features interfaces UART, SPI, I2C, 6 x DIO,
2 x analogue; AT-style control command; and transparent interfaces for RS232,
RS485 cable replacement applications.
The MultiConnect mDot, 900MHz LoRa based RF
modules are available from Elecom Electronics Supply.
