The Wi-FIRE, which is designed around Microchip's latest MZ architecture and Imagination Technologies Flow Cloud, enables rapid prototyping using the Arduino IDE. The PIC32MZ family provides 2.5x the performance and 4x the memory over the PIC32MX family. The Wi-FIRE can also be programmed with the chipKIT PGM Programmer/Debugger.
