Atmel ATSAMD21-XPRO
SAM D21 Xplained Pro Evaluation Kit
The Atmel® SAM D21 Xplained Pro evaluation kit is ideal for evaluating and prototyping with the Atmel SAM D21 ARM® Cortex®-M0+ based microcontrollers. Several extension boards that add functionality to the SAM D21 Xplained Pro, such as WiFi & Bluetooth connectivity, motion sensing, displaye etc. can be purchased separately.
Supported by the Atmel Studio integrated development platform, the kit provides easy access to the features of the Atmel SAMD21J18A microcontroller and explains how to integrate the device in a custom design. The Xplained Pro MCU series evaluation kits include an on-board Embedded Debugger and no external tools are necessary to program or debug the SAMD21J18A MCU. The Xplained Pro extension kits offers additional peripherals to extend the features of the board and ease the development of custom designs
