Development board for AT91SAM7 ARM7TDMI-S microcontroller - the universal board enabling easily and quickly to start to work with ATMEL ARM microcontrollers.

The presence of multiple interfaces on the board make the board useful not only for beginners, but for experienced programmers, providing an opportunity to start writing software even before they appear "hardware" of the project.
The board allows a developer to download via RS-232 or USB custom program, to connect an external JTAG-emulator. It comes with everything needed for quick start components, and provides an opportunity to build the scheme at the prototype area, expanding and without that a great board opportunity.
