2. Getting Started 2.1. Xplained Pro Quick Start Three steps to start exploring the Atmel Xplained Pro platform: 1. Download Atmel Studio. 2. Launch Atmel Studio. 3. Connect a USB cable (Standard-A to Micro-B or Micro-AB) between the PC and the DEBUG USB port of the board. When the Atmel SAME70-XPLD is connected to your computer for the first time, the operating system will ® perform a driver software installation.
3. Xplained Pro Xplained Pro is an evaluation platform that provides the full Atmel microcontroller experience. The platform consists of a series of Microcontroller (MCU) boards and extension boards, which are integrated with Atmel Studio, have Atmel Software Framework (ASF) drivers and demo code, support data streaming, and more. Xplained Pro MCU boards support a wide range of Xplained Pro extension boards, which are connected through a set of standardized headers and connectors.
3.3. Data field Data type Example content Minimum Voltage [mV] uint16_t 3000 Maximum Voltage [mV] uint16_t 3600 Maximum Current [mA] uint16_t 30 Power Sources The SAME70-XPLD kit can be powered by several power sources listed in the table below. Warning: The 3.3V power domain is locally generated and must never be supplied from external sources or this would damage the on-board regulators.
The extension headers can be used to connect a variety of Xplained Pro extensions to Xplained Pro MCU boards or to access the pins of the target MCU on Xplained Pro MCU boards directly. Table 3-3 Xplained Pro Standard Extension Header 3.5.

4.3.5. J302 Pin Mnemonic Pin on SAM E70 SAM E70 Signal Name Signal Description 4 ID -- -- On-the-go identification 5 Ground GND GND System Ground Current Measurement Header (VCC_MCU_P3V3 ) A 100mil pin-header marked "J203" is located at the upper edge of the SAME70-XPLD. All the power going to the ATSAME70Q21 is routed through this header. To measure the power consumption of the device, remove the jumper and replace it with an ammeter.
Caution: Leaving J201 open while the main power source is present is to be avoided. This would feed all power pins of the ATSAME70Q21 except VDDCORE, which may cause permanent damage to the device. 4.3.7. Chip Erase Header The chip erase header J200 is connected to the SAM E70 erase pin (PB12) and the main 3.3V. To erase the contents of the SAM E70 flash memory, set a jumper on J200 and turn the power supply on. The jumper can be removed soon after the power is on (flash erasing takes only 200ms).
