3.3 Xplained Nano Standard Pinout
Xplained Nano kits have a standard pinout in the mEDBG section, as shown in the tables and figure below. The program/debug pins will change depending on the target interface but will remain at the same locations.
Xplained Nano kits have a target section where all I/O pins will be available and fanned out. Except for the VCC and GND pins with fixed positions, there are no defined pin functions in this area. The first pin in the target area is the VCC pin, located right next to the VREG pin of the standard section. The last pin is GND, and it is located next to the CDC RX pin in the standard section. For reference, see the figure below.
