UDOO X86 II is the New PC: the most powerful maker board ever and an Arduino™ Leonardo-compatible platform, all embedded on the same board.

On UDOO X86 you can run all the software available for the PC world, from gaming to video streaming, from graphical editors to professional development platforms, plus all the software for the Arduino™ Leonardo world, including all the sketches, libraries and the official Arduino™ Leonardo IDE.

UDOO X86 embeds two processors:

  • a Quad Core 64-bit new-generation x86 Braswell 14nm processors, designed for the PC domain (The N-Series Intel® Pentium® / Celeron® and x5-Series Atom family of System-on-Chips (SoCs) formerly coded as Braswell is a series of Quad Core SoCs with 64-bit instruction set and very low TDP.)
  • the Microchip ATmega32U4 8-bit AVR microcontroller, the same of Arduino® Leonardo.

While the X86 Braswell processor can run all the Windows, Linux, Android X86 64bit Distros you want to use as desktop PC, the ATmega32U4 allows easy access to a Arduino™ Leonardo environment.

Download the User Manual to have more complete explanation of the UDOO X86 hardware.

Visit the Get Started X86 section of the UDOO website to find video tutorials of how to start use the UDOO X86 board.

This is the documentation for the second revision of the UDOO X86 - UDOO X86 II - board with Arduino Leonardo-compatible microcontroller (ATmega32U4).
If you have the first UDOO X86 revision in your hands, please consult the UDOO X86 doc at this page. Check how to recognize the UDOO X86 revision.

If you have any trouble uploading the Arduino sketch running Linux, check the Linux Known issue - Sketch upload section in the Getting Started with Arduino Leonardo page.

Heads up! In order to prevent damages to your board, remember to:

  • Never provide more than 5V in input to the GPIOs of the Arduino Leonardo-compatible(Atmel® ATmega32U4), and never provide more than 1.8V in input to the GPIOs of the Braswell processor.
  • Never keep the board in touch with metal objects or surfaces while it is powered up
  • Power the board with a stabilized power supply (DC-jack with a standard 5.5mm/2.1mm barrel jack, internal positive, Voltage 12V ± 5%, at least 3A).
  • Do not use a NON-standard USB 3.0 peripheral. If you use a non-standard USB 3.0 peripheral with an external power plug, this could send back the power source to the UDOO X86 board with the risk of damage.
