PIC32 Pinout

This document provides a pinout diagram and descriptions for the Microstick II development board featuring a PIC32MX250F128B microcontroller. It identifies the functions of each pin including digital and analog I/O, programming and power pins. Tables are included that show which peripheral functions can be assigned to each pin through configuration registers. This allows developers to understand how to interface sensors, displays and other hardware to the pins of the microcontroller on this board.
