iMX233-OLinuXino-Micro – 76×42 mm Single Board Linux Computer!


Today we made the preliminary schematic of iMX233-OLinuXino-MICRO, the smallest OLinuXino single board computer.

It will be 2 layers design in very compact form, on the left side you see the TV-OUT + USB-host where you can connect Keyboard, Mouse or WIFI dongle, on the right side you see the SD-card and miniUSB which is used as power supply 5V connector.

My rough estimations are that the BOM of this board will be around EUR 12 even for small quantities like 100 pcs, our plans are to release assembled and tested module for EUR 19.95.

Two 0.1″ step 30 pin rows connectors have all iMX233 signals and you can use breadboard like BREADBOARD-1 to breadboard your next LINUX project at home 🙂

Specifications remain iMX233 454Mhz ARM9 processor, 64MB RAM.

The CAD files are on the usual place in GitHub:

    And this way, is a visible difference between boards. It definitely looks very difficult to route!
    A nice board to replace a PC in feeding an USB CNC Router controller. And not only that, of course.

    Hi. I wanted to know as to how you go about deciding the RAM size? Does it depend on the clock speed of the CPU?
    Secondly, why did you go for a 64 MB RAM? Low-cost boards like Raspberry Pi are providing 256 MB RAM. Why not try to match them?

      RAM size do not depend of the clock, the 64MB is the max this chip can address

        You did not answer about matching the Raspberry Pi part. I am sorry if I sound nagging. I don’t intend to. I am just curious.

        I’m not sure I understand your question, as I wrote iMX233 can address up to 64MB of RAM. So what do you ask – why you didn’t build board with 256MB of RAM with processor which can address only 64MB RAM? you can read on this blog some post down there is A13 board in design stage which will have 512MB RAM, sorry it will not match RPi memory footprint again 😉

        Hi. Sorry for being unclear. I meant to ask as to why you chose this processor if it has a lower RAM addressing capability. I read the post about A13 board. I now understand that everything is not about competing with RPi 😛

        As of the A13 board, It should be good competition for BeagleBoard-xM! Or better – with the rise of tablet computers and portable devices – if you can make a development platform with common peripherals like a YUYV-output camera, capsense module etc., it will be a wonderful tool for developers like me!

        please read the README on to understand why we decided to make board with iMX233
