ATSAMR21ZLL-EK
SAM R21 ZigBee Light Link Evaluation Kit

The AtmelŪ ATSAMR21ZLL-EK evaluation kit is a hardware platform to evaluate the ATSAMR21G18A microcontroller. Supported by the Atmel Studio integrated development platform, the kit provides easy access to the features of the Atmel ATSAMR21G18A and explains how to integrate the device in a custom design. The ATSAMR21ZLL-EK evaluation kits include an on-board Embedded Debugger, and no external tools are necessary to program or debug the ATSAMR21G18A. This Evaluation Kit supports antenna diversity, RGB led, QTouch Interface, OLED display, Joystick, user LEDs, user switch, external USB, UART interfaces and Atmel Xplained pro extension header.
