Board v0.3
3.2.2 P2 Connector
P2 connector is a standard 2.54mm (0.1 inch) pitch header, with 1 row of 10 pins, and can be populated using
either male or female header, and mounted either on top or on bottom side of the board.
P2 connector provides access to USB +5V power supply, ADC, and GPIO pins from port 0 and 1 of the LPC
micro-controller.

3 – P2 Connector Pinout
Note
: Most P2 pins also provide alternate capture or match input functions for 32-bit timers. Refer
to the LPC1224 documentation from NXP for full documentation of the alternate functions.
Note
: When the board is not connected to a power source on the USB port the +5V is not present
on pin 1 of P2 connector.
3.2.3 P6 and P7 Connectors
P6 and P7 are one-time choice options. Only one of them is present, depending on the board type. Both are
standard USB connectors. P6 is a female micro-AB port, and P7 is a male USB-A port.
Refer to the
Universal Serial Bus (USB)

page on Wikipedia for pinout and more information on the USB bus and
connectors.
