The Fubarino® Mini is a prototyping-friendly platform for developing Arduino compatible 32-bit applications. Compact size (5.1 cm x 1.9 cm) and low cost allow the Mini to fit almost anywhere. (It’s actually much smaller than a stick of gum!) Includes a USB bootloader that works with the chipKIT/MPIDE platform. Connect directly to your application using solder pads, or add the male expansion headers and plug into a breadboard.

The Fubarino™ Mini is a small microcontroller board that uses a powerful PIC32 microcontroller. It is chipKITTM/MPIDE compatible and can run the same sketches that run on an ArduinoTM. It is designed to have all I/O pins on either side of the board in a traditional DIP pattern so that it can easily be plugged into a breadboard. It has a USB connector for power, programming, and a connection to a PC.

Before you can compile and upload a sketch to the Fubarino Mini, you must put it into programming mode. This is very simple - simply press and hold the PRG button while you press and release the RESET button. Then release the PRG button. If programming mode was successfully entered, the green LED will rapidly blink. You can then click the Upload button (right pointing arrow) in MPIDE and if your code compiles properly, it will be uploaded.

Note that the serial port that MPIDE uses to upload new code to the Fubarino Mini board does not exist until you put the board into programming mode. So it will not show up in the Tools->Serial Port menu until you put it into programming mode.

The Fubarino Mini is small 33 pin Arduino API compatible board with a difference. The PIC32MX250 part used on Fubarino Mini has a Peripheral Pin Select function for almost all of its I/O pins. When writing sketches for the Fubarino Mini, you must remember to connect an internal peripheral (like SPI or UART) to a particular set of I/O pins using the PPS functions (ppsInputSelect() and ppsOutputSelect()) before trying to use the peripheral.
