Building on the previous successes with the WF32, the Wi-FIRE uses the same 43 available I/O pins, 12 analog inputs, 3.3 operating voltage, 4 user LEDs, potentiometer, buttons, uses MRF24 on-board wireless module, microSD Card, dedicated SPI Signals and high efficiency switching 3.3V switching power supply for low-power operation.

Where the boards differ is in what the PIC32MZ processor can deliver.

The Wi-FIRE is significantly faster than its WF32 counterpart, with 200 MHz operation speed, 2MB of Flash, 512kB RAM, High-Speed USB and a 50MHz SPI. The PIC32MZ core includes the MIPS M5150 CPU Core from OpenOCD.

The Wi-FIRE can be programmed using MPIDE and with the addition of a compatible in-system programmer/debugger, can be used with the more fully featured/advanced Microchip MPLAB® X IDE.
