-The production boards of the Wi-FIRE are manufactured using the Microchip PIC32MZ2048EFG100 MCU. Earlier pre-production, Rev B and earlier, uses the PIC32MZ2048ECG100 MCU. The MCUs are pin for pin compatible, however the PIC32MZ2048EFG100 has substantially improved ADCs, and there is an FPU coprocessor. For the most part, code written to the pre-production Wi-FIRE will run unaltered on the Rev C or newer Wi-FIREs, with the exception of the ADCs. The Digilent core will support either MCU, even with respect to the new ADCs, as long as the chipKIT hardware abstraction API, analogRead(), was used; no sketch source code change is required. The production PCB is identical between the Rev B and Rev C, with the exception of the silk screen to indicate Rev C. +The production boards of the Wi-FIRE are manufactured using the Microchip PIC32MZ2048EFG100 MCU.

 Rev D boards now include a new header for MIPS JTAG debugging and iFlowtrace and a few hardware changes to support this connector. Most components on the board remained the same, although nearly all of the silk screen designators were changed from Rev C. Rev D boards now include a new header for MIPS JTAG debugging and iFlowtrace and a few hardware changes to support this connector.

-The chipKIT Wi-FIRE is based on the popular Arduino™ open-source hardware prototyping platform and adds the performance of the Microchip PIC32MZ microcontroller. The Wi-FIRE has a WiFi MRF24 and SD card on the board, both with dedicated SPI signals. The Wi-FIRE board takes advantage of the powerful PIC32MZ2048EFG microcontroller. This microcontroller features a 32-bit MIPS M5150 processor core running at 200 MHhz, 2MB of flash program memory, and 512K of RAM data memory. The Wi-FIRE can be programmed using the Arduino IDE with the Digilent Core. It contains everything needed to start developing embedded applications. The Wi-FIRE features a USB serial port interface for connection to the Arduino IDE and can be powered via USB or by an external power supply. In addition, the Wi-FIRE is fully compatible with the advanced Microchip MPLAB®X IDE and works with all MPLAB ®X compatible in-system programmer/debuggers, such as the Microchip PICkit™3 or the Digilent® chipKIT PGM. The Wi-FIRE is easy to use and suitable for both beginners and advanced users experimenting with electronics and embedded control systems. +The Wi-FIRE is based on the popular Arduino™ open-source hardware prototyping platform and adds the performance of the Microchip PIC32MZ microcontroller.

 Note: The I2C bus uses open collector drivers to allow multiple devices to drive the bus signals. This means that external pull-up resistors must be provided to supply the logic high state for the signals.  Note: The I2C bus uses open collector drivers to allow multiple devices to drive the bus signals.

-Some Arduino shields, most notably the Ethernet shield, connect pin 5 to the reset net on pin 3 of connector J1. This causes the processor to be reset each time an attempt is made to access the SPI port. Jumper JP3 can be used to break the connection between J8 pin 5 and reset when using Arduino shields that make this connection. JP3 has a cuttable trace on the top of the board that can be cut to break the connection between SPI SS and reset. JP3 is not loaded at the factory.
