Microchip Technology SAM E54 Xplained Pro - Headers and Connectors

2. Embedded Debugger USB.
3. Target USB.
Info: External power is required when 500mA from a USB connector is not enough to power
the board with possible extension boards. A connected USB device in a USB host application
might easily exceed this limit.
4.5 Xplained Pro Headers and Connectors
4.5.1 Xplained Pro Standard Extension Header
All Xplained Pro kits have one or more dual row, 20-pin, 100-mil extension header. The Xplained Pro
MCU boards have male headers, while the Xplained Pro extensions have their female counterparts. All
connected pins follow the defined pin description in the table.
Info: All pins are not always connected on all extension headers.
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 microcontroller on Xplained Pro MCU boards directly.
