Open source hardware board
Nixduino is a convenient and affordable solution for an open platform to run Linux. Developments of Nixduino were used in the project Celebrity.
Application options vary, since you can connect keyboards, headphones, flash-drive and etc. For example, one of the developers used Nixduino as an mp3 player. As a prototype there were realized devices for building into the automobile headrests, which are adapted for playing various media files.
If you plan to introduce some extensions of the architecture - board is completely compatible with Arduino.

The hardware task includes developing of schematic diagrams of the printed circuit board. It was initially supposed to make a double-layer board, but later it became a four-layer to ensure a high quality of power supply of the processor IMX 233 (TQFP). With the help of a USB convertor based on UART ( FTDI ) console access to Nixduino is performed.
- the microcontroller i.MX233 (core ARM926EJ–S) (frequency 454 MHz)
- RAM DDR 64 MB
- NAND flash 128 MB
- power 6-20 V (from the USB connector, the VIN pin or Li-ion battery)
Build of Linux with appropriate settings and additional tools.
- analog TV out,
- different connectors (for the headphone, keyboard, microphone, USB)
- built-in power converter that can either operate from a battery, or make himself a power supply that produces charging,
- console access via FTDI
