A closer look at Atmel’s SAM D20 Xplained Pro eval kit

Atmel’s SAM D20 lineup is based on the ARM Cortex- M0+ core, setting a new benchmark for flexibility and ease-of-use. The recently launched MCU series is ideal for a number of low-power, cost-sensitive industrial and consumer devices, such as GPS trackers, appliance controllers, intelligent remotes and optical transceivers.

Perhaps most importantly, the SAM D20 also offers engineers easy access to an expansive array of software and hardware tools, including Atmel Studio 6 (free IDE with compiler) as well as the SAM D20 Xplained Pro evaluation kit.

The $39  kit supports the Atmel I/O1 Xplained Pro, OLED1 Xplained Pro and PROTO1 Xplained Pro extension boards, all of which can be purchased individually.


In terms of key specs, the board is powered by a SAMD20J18 microcontroller and features one mechanical reset button, a single mechanical user pushbutton (wake-up, bootloader entry or general purpose), a yellow user LED, 32.768kHz crystal and three Xplained Pro extension headers.

Additional specs include an embedded debugger, Auto-ID for board identification in Atmel Studio 6.1, one yellow status LED, one green board power LED, Data Gateway Interface (SPI, I²C, 4 GPIOs) and a virtual COM port (CDC).
