The Arduino M0 Pro, a simple and powerful extension of the 32-bit Arduino platform established by the Arduino Uno board is now on sale at RS Components. Aimed at embedded engineers, hackers and students, the Arduino M0 Pro board is designed to help the development of innovative ideas for smart Internet-of-Things (IoT) devices, wearable technologies, high-tech automation, robotics and other imaginative projects.

As well as enabling new project opportunities, the board is highly suitable as an educational tool for learning about 32-bit application development.

Fuelled by the low-power Atmel SAM D21 microcontroller, which integrates the 32-bit ARM Cortex® M0+ core, the Arduino M0 Pro board expands the Arduino family with increased performance and a highly flexible feature set.

A key feature of the board is the Atmel Embedded Debugger (EDBG), which provides a full debug interface without the need for additional hardware and significantly increases ease-of-use for software debugging. The EDBG also supports a virtual COM port that can be used for device programming and traditional Arduino boot loader functionality.

Compatible with 3.3V shields that conform to the Arduino R3 Layout, development using the Arduino programming language is fully supported through a custom developed software library, integrated in the Arduino development environment.

Key hardware specifications of the M0 Pro board include: ATSAMD21G18 MCU running at 48MHz and packaged in a 48-pin LQFP, 3.3V operation, 256KB of Flash memory, 32KB of SRAM and EEPROM of up to 16KB via emulation. Input/output options include 14 digital I/O pins with 12 PWM channels and UART, six 12-bit ADC input channels and a 10-bit DAC output.
