Processor Plug-In Modules are small circuit boards to be used with the various Microchip Development Boards to evaluate various MCU families. These plug into the main processor socket of the Development Boards so that different microcontrollers can be used for prototyping, demonstration or development --quickly and easily.

The PIC32MX250F128D PIM is designed to demonstrate the capabilities of the PIC32MX1XX/ 2XX family of devices using Explorer 16 Development Board. It enables USB and graphics development with the PIC32MX2XX series.
