I just got an Atmel XMEGA-A1 Xplained evaluation board and I'm trying to get started, but the documentation is a bit confusing to me.
Page 6 Section 4 has this warning.
Do not power the board without having the jumper attached next to the USB connector or an ammeter mounted. Otherwise, the device may be damaged by power sourcing through I/O pins. The power measurement header is located next to the USB connector, as shown in Figure 3-1.
But I don't know what a jumper is. How do I safely turn this thing on?
To clarify, I see the part on the board labeled "Power Jumper" in the diagram, but I don't know what it means by "attached". It's soldered into the board, how could it not be attached? Alternatively, how would I mount an ammeter?
I spent a bit of cash on this thing and want to be sure I don't fry it before I've had a chance to write a single line of code for it.
