The chipKIT™ Pro MX7 is a microcontroller development board based on the Microchip PIC32MX795F512L, a member of the 32-bit PIC32 microcontroller family. Designed to be easy-to-use, it is suitable for use by anyone from a beginner to an advanced user experimenting with electronics and embedded control systems. Inherently, it is compatible with chipKIT-core™ development environment and Arduino IDE, but since it also has a built-in, on-board Microchip programming/debugging circuit it is compatible with MPLAB® X IDE with no additional hardware required to program or debug.

In addition, the chipKIT Pro MX7 is compatible with Digilent’s line of Pmod™ peripheral modules. chipKIT products and the MPIDE are part of a PIC32-based system compatible with many existing Arduino™ code examples, reference materials, and other resources.
