The chipKIT DP32 is the first chipKIT rapid prototype project board from Digilent. It uses chipKIT-core™ development environment and Arduino IDE for compatibility with existing code examples, tutorials and resources. The board adds the power of the Microchip PIC32MX250F128B with a prototyping area in a single board.


The Board Design

  • Microchip PIC32MX250F128B microcontroller (40/50 MHz 32-bit MIPS, 128K Flash, 32K SRAM)
  • 15V maximum input voltage
  • 19 available I/O pins
  • 9 analog inputs
  • 1 Potentiometer connected to an analog input
  • Four user LEDs
  • Two user push button
  • Prototyping area
