1. INTRODUCTION
DuinoMite
is a series of compact development boards based on the
PIC32
microcontroller from
Microchip Technology Inc.
The
DuinoMite
is a complete computer, running a BASIC interpreter called MM-Basic (originally
written by Geoff Graham), which when interfaced with a PS2 keyboard and VGA monitor, is
reminiscent of the old retro APPLE][ and TRS-80 personal computers. No need for a PC, no need for
compilers IDEs, programmers, all you need to write embedded applications is
DuinoMite.
DuinoMites
have ARDUINO shield connectivity, allowing ARDUINO shields to be directly interfaced,
making the
DuinoMite
the world's first stand alone ARDUINO Single Board Complete BASIC
computer .
DuinoMite
is a completely open source platform and the schematic and board files are available for
download from the Olimex (www.olimex.com) web site and released under the
Creative Commons
Attribution-Share Alike 3.0 United States License
, which generally means that you are free to use these files
to create your own product providing you credit Olimex as the source and release your files with the
same license as well.
The heart of
DuinoMite
is the
PIC32MX795F512
which, amongst others, includes the following
features: On-Chip: 80Mhz clock operation, 512KB Flash memory, 128KB RAM memory, USB with
OTG functionality, UARTs, SPIs, I2C, ADC, CAN, PMP.
Three
DuinoMite boards are in production:
DuinoMite-Mega
DuinoMite-Mini

http://www.olimex.com/dev/DUINO/duinomite.hrml
and two more boards are in design phase at the current date:
DuinoMite-eMega
board with Ethernet, Internal Flash and PMP, with possibility for color VGA output.
PIC32-T795
which is a low cost, general purpose, development board for easy bread-boarding using
wire jumpers.
2. BOARDS
2.1. DuinoMite-Mega
This is, to date, the most sophisticated board from
DuinoMite
range of boards.
The schematic of the current revision of the
DuinoMite-Mega
can be found online in the DUINO
section at
http://www.olimex.com/dev,
you will also find the CAD schematics and board files.
DuinoMite-Mega
is available for sale as either a pre-assembled board only or alternatively, in a laser
cut, custom made plastic enclosure:
