The Atmel
SAMHA1G16A Xplained Pro evaluation kit is a hardware
platform to evaluate the ATSAMHA1G16A microcontroller.
Supported by the Atmel Studio integrated development platform, the kit
provides easy access to the features of the Atmel ATSAMHA1G16A 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 ATSAMHA1G16A.
The Xplained Pro extension kits offers additional peripherals to extend the
features of the board and ease the development of custom designs.
