chipKIT™ Pi (Designed for Raspberry Pi) is the latest Arduino™ compatible chipKIT platform from Microchip and element14. It features a 32-bit PIC32 microcontroller in a prototyping-friendly, low pin count SPDIP package. The PIC32s performance, memory and integrated peripherals allow users to create applications including touch sensing, audio processing and advanced control. The board is supported by the free chipKIT Multi-Platform IDE MPIDE that can be hosted on the Raspberry Pi.
