Charlie is compatible with the Arduino MKR form factor board, combining a low-power ARM® Cortex®-M0 32-bit SAMD21 microprocessor with our ME310 cellular module, which provides global cellular narrowband connectivity with a high-performance GNSS receiver.

The kit includes a Bosch Sensortec high-performance motion smart sensor chip and an embedded GNSS antenna, making Charlie a complete yet extremely compact IoT development platform.

Charlie can be used either alone or expanded with compatible shields. The Charlie kit provides the most commonly needed building blocks to develop, prototype and deploy IoT applications.
