Revised March, 2015 
This manual primarily applies to Rev C, as found on the underside of the board next to the white bar-coded box. Rev C is a major change
from Rev B, so differences will be noted where appropriate.

The chipKIT DP32 is an MPIDE compatible prototyping and project development board from Digilent. It combines the power of the
Microchip® PIC32MX250F128B 28-pin DIP with a wire wrap prototyping area, provision for an EEPROM () non-volatile memory, and
analog temperature sensor, a potentiometer, buttons and LEDs in a single board. The mounting hole footprint on the board is designed
to fit in the Hammond 1591XXSSBK project box.

The DP32 takes advantage of the powerful PIC32MX250F128B microcontroller. This microcontroller features a 32-bit MIPS processor
core running at 40 MHz (), 128K of flash program memory and 32K of SRAM data memory. It is suitable for building projects directly
on the board utilizing the provided prototyping area, but it can also be used as a device programmer to program the microcontrollers for
inclusion in custom built projects.

The DP32 can be programmed using the Multi-Platform Integrated Development Environment, MPIDE, an environment based on the
open source Arduino™ IDE modified to support the PIC32 microcontroller. The board provides everything needed to start developing
embedded applications using the MPIDE.

The DP32 is also fully compatible with the advanced Microchip® MPLAB X® IDE. To develop embedded applications using MPLAB
X, a separate device programmer/debugger, such as the Digilent chipKIT PGM or the Microchip PICkit3™ is required.

Features Include:

Microchip PIC32MX250F128B 28-pin DIP microcontroller (40/50 MHz () 32-bit MIPS, 128K Flash, 32K SRAM)
5 – 12 Volt recommended operating voltage
