86Duino is an open-source embedded platform based on Vortex86EX SoC, easy-to-use hardware and software integrated. This Arduino-compatible board can support many x86 O/S as well as those running on the original Arduino base system. The 86Duino is a high performance and fully static 32-bit x86 processor board compatible with Windows OS, Linux and most popular 32-bit RTOS. It integrates PCIE bus, DDR3, ROM controller, xISA, I2C, SPI, IPC (Internal Peripheral Controllers with DMA and interrupt timer/counter included), Fast Ethernet, FIFO UART, USB2.0 and SD/SATA controller within a single package to form a system-on-a-chip (SOC).  86Duino provides an ideal solution for the Arduino and embedded system with desired performance.

The company provides support for DOS, Linux, Windows Compact 7.0, QNX and VxWorkx for their Vortex86EX processor. A custom Arduino IDE, called 86Duino IDE, is available for Windows and Linux. Schematics (PDF and Allegro), BoM, and Gerber files are available for the daughter board, and the SoM’s schematics (PDF) are also provided. The company claims this is an open hardware board, but if that’s all they provide, they’re not fully compliant. Nevertheless, hardware files, tools, and application samples are available via github.

The company also have two other products featuring Vortex86EX SOM-128-EX:

  • 86Duino One – Similar to 86Duino ZERO for with more I/O including 11 PWM outputs to control servos. It also supports 6 to 24 V input, and comes with with extra Line-out and  Microphone ports. The PCIe connector is moved at the back of the board (Mini PCIe connector). Finally there’s a CR2032 battery for the RTC in the SoM.
  • 86Duino EduCake – This product is also Arduino compatible for software, but not for the header. It features a daughter board and a breadboard connected with the SoM, all placed into an enclosure. External ports include 2x USB ports, an SD card slot, headphones and microphone jacks, an Ethernet port, a DB9 COM port, and a micro USB port for power and development. The breadboard is accessible via the top of the enclosure as shown in the picture below.
