The chipKIT™ Platform is an open-source hardware and software solution intended for beginners and users who wish to explore embedded applications with little or no knowledge of embedded controllers.
The chipKIT module is based on the Microchip PIC32 microcontroller. The module is code compatible with the Arduino so all the Arduino sample programs can run on the chipKIT.
For those that want the simplicity of Arduino code but the power of a 32 bit processor, then chipKIT is for you.
