SAM C21 Xplained Pro Evaluation Kit

The Atmel® SAM C21 Xplained Pro evaluation kit is a hardware platform for evaluating the Atmel ATSAMC21J18A microcontroller (MCU).

Supported by the Atmel Studio integrated development platform, the kit provides easy access to the features of the ATSAMC21J18A and explains how to integrate the device into a custom design.

The Xplained Pro MCU series evaluation kits include an on-board Embedded Debugger, eliminating the need for external tools to program or debug the ATSAMC21J18A. The kits offers additional peripherals to extend the features of the board and ease the development of custom designs.
