In the world of IoT, everything starts at the edge, with the devices and the data they generate: that’s The First Mile of IoT™. Start your IoT journey from The First Mile with Charlie, the complete, ready-to-use Telit evaluation kit.
The next generation of Telit IoT evaluation kits, Charlie is an Arduino-based MKR form factor board. It combines a low power ARM® Cortex®-M0 32-bit SAMD21 microprocessor with a Telit ME310 cellular module, providing global narrowband connectivity and a highperformance GNSS receiver.
Charlie includes a Bosch Sensortec high-performance motion smart sensor chip and an embedded GNSS antenna to make it a complete yet extremely compact IoT development platform.
Charlie can be used either alone or expanded with Arduino-compatible shields and provides all building blocks to develop, prototype and deploy IoT applications.
