Fubarino™ Mini Reference Manual

Last Revision: April 7th, 2014

Introduction:

The Fubarino™ Mini is a small microcontroller board that uses a powerful PIC32 microcontroller. It is

chipKIT

/MPIDE compatible and can run the same sketches that run on an Arduino

. 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.

Features:

• PIC32MX250F128D-50I/ML microcontroller, which includes 128KB Flash and 32K RAM

• Supported as development target from within MPIDE

• Max 33 I/O pins (normally 27)

• Pads for 32 KHz crystal

• CPU runs at 48MHz

• USB connector for power, programming, and connection to PC (serial, mass storage, etc.)

• Two buttons: RESET for resetting the board, and PRG for getting into bootloader mode and user

application use

• USB bootloader pre-programmed at the factory – no other hardware needed to program board\

• Separate ICSP connector – for hardware programming/debugging with PICKit3 or other ICSP

programmer (not needed for use with MPIDE environment)

Fubarino™ Mini Reference Manual Last Revision: April 7th, 2014 Introduction: 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.

Figure 1 : Fubarino™ Mini Pin Map Entering Bootloader Mode To enter bootloader mode (also called programming mode) simply press the PRG button while pressing and releasing the RESET button. As long as the PRG button is held down when the RESET button is released, the bootloader will start waiting for a new program to be downloaded over USB. It will wait indefinitely. The bootloader on the Fubarino™ Mini implements the avrdude STK500 v2 protocol, just like the other chipKITTM/MPIDE boards.

menu. Then, put the Fubarino Mini into bootloader mode (see above), and then select the proper serial port in the Tools->Serial Port menu. After you enter your sketch and click the Upload button, MPIDE will compile your sketch and upload it to the Fubarino Mini. After the upload is complete, the Fubarino Mini will automatically reset and immediately begin running your sketch code. This includes sending information to the USB serial, UART1, and UART2.

boards. Make sure to select “Fubarino Mini” from the MPIDE Boards->Fubarino menu for version 1.5 boards. Peripheral Pin Select 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.

Developers The Fubarino series of boards were developed by Rick Anderson of FubarLabs and Brian Schmalz of Schmalz Haus LLC. They are registered chipKITTM boards and are designed to be programmed with the MPIDE system.
