Board Overview
Figure 1.
CryptoAuth Xplained Pro Extension Board
Optional XPRO Header
CAXPro optionally allows an additional XPRO male header to be mounted which allows additional
extensions such as a WIFI module or smart sensor. All XPRO connections pass through from one port to
the other with the exception of the ID signal. The ID Jumper is used to select which of the two boards will
be identified by ASF. The default position shown in Figure 1 selects the CAXPro board ID Chip.
Atmel Studio Framework (ASF) ID Device
All Xplained Pro compatible extension boards have an Atmel ATSHA204A crypto authentication chip
mounted. This chip contains information that identifies the extension with its name and some extra data.
When an Xplained Pro extension board is connected to an Xplained Pro MCU board the information is
read and sent to Atmel Studio via the SWI over the ID signal. For the board to be detected the ID jumper
must be connected as shown in Figure 1. Once connected to ASF, this board will be identified as a
CAXPro extension board. It will load the appropriate:
Atmel CryptoAuthentication example projects and software libraries.
Example projects and software libraries associated with the attached microcontroller board.
