Hi,

  Would someone be kind enough to point me to the schematics and any documentation of things like what the four pads near the USB socket are for?  I have just bought an R3 and find that the obvious schematics on the website do not match the hardware that I have.

  Thanks in advance, Brian.

They seem to connect to the 16U2 pins 18, 19, 20, 21, for who knows what.
Maybe general purpose I/O for future expansion.
