Here is the silkscreen and schematic on Rev 0.10:

Here is the Arduino Leonardo pinmap. Does everything match? Is the silkscreen accurate?
Are you sure the above pin mapping suitable for our project? As I found T400 dos not connect UVcc to +5V and datasheet of ATmega32u4 also suggest not connect +5V to UVcc while I/O using 3.0V to 3.6V.
Reference: (Page 256) http://www.atmel.com/images/doc7766.pdf
The image I reference above is for the Arduino Leonardo. It is only used to correlate between physical pins on the ATmega32U4 and their Arduino digital/analog designations.
Don't worry about it, I'll take care of this issue.

Yes, the Digital and Analog pin mapping are match with T400
Here is the pinmap for the current version of the T400. The pinmap, schematic, and silkscreen all match.

All good. Closing issue.
Make sure the Arduino pinmap on the silkscreen is accurate. This should be the last issue addressed before ordering PCBs.
