All Xplained Pro extension boards come with an identification CryptoAuthentication™ chip (ATSHA204A) to uniquely identify the boards that are connected to the Xplained Pro evaluation kit. This chip contains information that identifies the extension by its name and other additional data. When an Xplained Pro extension is connected to an Xplained Pro evaluation kit, the information is read and sent to Atmel Studio. The following table shows the data fields stored in the ID chip with example content.
