4.1.2 UC3C-Specific Information
4.1.2.1 AT32UC3C0512C Power Supply Mode
Among the two power supply configurations supported by the Atmel
AT32UC3C0512C, this board implements the 3.3V Single Supply Mode
configuration. Refer to the Figure “3.3V Single Supply mode” of the Power
Considerations section in the AVR UC3 C0 Series datasheet
for schematic diagram
of this mode.

4.1.3 Configurations and Test Points
4.1.3.1 Hardware Configurations
The default hardware configuration of the Power Supply block implies that:
• The power supply source is one of the 2x USB plug –“USB USER” and “USB
VCP”- or the jack header (ref. Figure 4-1 and Figure 3-1),
• The 2-pins header (J2) can also be used as a power supply source (not available
by default).
Mount the 0 Ohm R73 resistor (solder strap) and remove the 0 Ohm R71 resistor, to
enable the 2-pins header external entry (J2).
