1.2. Kit Overview Atmel I/O1 Xplained Pro extension board is a generic extension board for the Xplained Pro platform. It connects to any Xplained Pro standard extension header on any Xplained Pro MCU board. The extension board utilizes all functions on the standard Xplained Pro extension header to further enhance the feature set of Xplained Pro MCU boards. -

, Windows 7, and Windows 8. Once the Xplained Pro MCU board is powered the green power LED will be lit and Atmel Studio will auto detect which Xplained Pro MCU- and extension board(s) are connected. Atmel Studio will present relevant information like datasheets and kit documentation. -

When an Xplained Pro extension is connected to an Xplained Pro MCU board the information is read and sent to Atmel Studio. The Atmel Kits extension, installed with Atmel Studio, will give relevant information, code examples, and links to relevant documents. - Page 6 SPI_MISO Master in slave out line of serial peripheral interface.

4.1. Electrical Characteristics I/O1 Xplained Pro can be connected to several Xplained Pro MCU boards and manually connected to other hardware. Xplained Pro MCU board(s) that does not have 3.3V as it's primary target voltage will read all ID devices on connected extensions to check if they support the target voltage before enabling it to the extension headers. -
Page 8: Power Header
VTG for target voltage and GND for ground. Info: The two pin power header should not be used to apply power to I/O1 Xplained Pro when connected to an Xplained Pro MCU board as it will get power from the Xplained Pro MCU board through the 20-pin extension connector. -

Peripherals 4.3.1. There is one yellow LED available on the I/O1 Xplained Pro extension board that can be controlled by Pulse Width Modulation (PWM) or regular GPIO operation. The LED can be activated by driving the connected I/O line to GND. -

100kΩ resistors, which makes the default addresses 0b1001111 and 0b1010111. Soldering the straps on the back of the I/O1 Xplained Pro board for An will alter that bit in the address to zero. Each strap is marked in silkscreen with A0, A1, and A2 as shown in the picture below. When communicating with the EEPROM parts of the TWI address is used as a page address. -

5.1. Identifying Product ID and Revision The revision and product identifier of Xplained Pro boards can be found in two ways; either through Atmel Studio or by looking at the sticker on the bottom side of the PCB. By connecting an Xplained Pro MCU board to a computer with Atmel Studio running, an information window will pop up. -
