chipKIT Uno32™ Prototyping Platform
Microchip® PIC32MX320F128
Application development using an environment based on the original Arduino™ IDE modified to support PIC32 that also still supports the original Arduino™ line. Compatible with many existing Arduino™ code examples, reference materials and other resources.

To download the IDE, please visit:

  • Microchip® PIC32MX320F128 processor
    • 80 Mhz 32-bit MIPS
    • 128K Flash, 16K SRAM
  • Compatible with many existing Arduino™ code examples, reference materials and other resources
  • Can also be programmed using Microchip’s MPLAB® IDE (along with a PICkit 3 and our PICkit3 Programming Cable Kit, seen below)
  • Arduino™ “Uno” form factor
  • Compatible with many Arduino™ shields
  • 42 available I/O
  • User LED
  • Connects to a PC using a USB A -> mini B cable (not included)
The chipKIT™ Uno32™ is based on the popular Arduino™ open source hardware prototyping platform but adds the performance of the Microchip PIC32 microcontroller. The Uno32 is the same form factor as the Arduino™ Uno board and is compatible with many Arduino™ shields. It features a USB serial port interface for connection to the IDE and can be powered via USB or an external power supply.

The Uno32 board takes advantage of the powerful PIC32MX320F128 microcontroller. This microcontroller features a 32-bit MIPS processor core running at 80Mhz, 128K of flash program memory and 16K of SRAM data memory.

The Uno32 can be programmed using an environment based on the original Arduino™ IDE modified to support PIC32. In addition, the Uno32 is fully compatible with the advanced Microchip MPLAB® IDE and the PICKit3 in-system programmer/debugger.

Heads up! Transit of Venus, 2012 June 5-6th

Transit of Venus in 6 days!
Transit of Venus: 2004-06-08 One of the rarest of celestial spectacles is the transit of the planet Venus in front of the disc of the Sun as viewed from the Earth. Indeed, this event did not occur at all in the twentieth century and takes place only twice in the twenty-first, the first of which, on June 8th, 2004, you’ve already missed. So it’s either catch the big show on June 5–6th of 2012 or plan to hang in there until the next transit of Venus on the 11th of December 2117.

    Astronomy Picture of the Day

    Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.

    2012 May 5

    Full Moonrise
    Image Credit & Copyright: Robert Arn
    Explanation: Rising as the Sun sets, tonight’s Full Moon could be hard to miss. Remarkably, its exact full phase (May 6 03:36 UT) will occur less than two minutes after it reaches perigee, the closest point to Earth in the Moon’s orbit, making it the largest Full Moon of 2012. The Full Perigee Moon will appear to be some 14 percent larger and 30 percent brighter than a Full Moon near apogee, the most distant point in the elliptical lunar orbit. In comparison, though, it will appear less than 1 percent larger and almost as bright as April’s Full Moon, captured in this telephoto image rising over suburban Fort Collins, Colorado, USA. For that lunation, Full Moon and perigee were about 21 hours apart. Of course, if you manage to miss May’s Full Perigee Moon, make a note on your calendar. Your next chance to see a Full Moon close to perigee, will be next year on June 23.
