The Metal Linux Computer – The first LCD industrial panel prototypes are ready


What you see is our first sample of the metal frame for 7″ LCD with build-in A20-OLinuXino-LIME inside!

Our mechanical designer is getting better and better after the design of A20-OLinuXino-MICRO and A20-OLinuXino-LIME boxes. The box for MICRO was done after three attempts, the LIME box was done right from the second attempt, now the LCD box got perfect from the very first attempt!

The metal frame is done by three parts:


Here above you see two parts, which connect together with single screw. Why this is necessary – LIME has connectors on both ends and it’s not possible to fit inside as the connectors go outside PCB borders


this is the third part it’s bend to hold inside the touch panel and LCD:


here is the frame with LCD and touchscreen in it:


the LIME is attached to back panel with one screw on metal spacer, the left side connectors show outside a bit:


then we attach the right side panel and screw them together:


then the LCD part is snap to the other two and fixed with 4 screws:


here is how it looks on the back side:


the same four mount holes can be used the metal panel to be assembled to other surface there are provisional mount holes on the back side as well.

The whole construction is solid and reliable. The frame dimensions are: 190 x 102 mm the higher back side is 40 mm the lower side is 10 mm thick.

This whole frame have approx same size as MODEL-B box and have just few more bendings so the price I expect is to be same as on MODEL-B box i.e. about EUR 15.00

This means 7″ LCD panel with A20-OLinuXino with the metal frame will cost from EUR 81.00 and if TOUCH screen is add from EUR 89.00

    Fantastic!, and I guess there is no sharp edges?, especially close to the screen?
    Is this screen the type you sell for the lime?

    same LCD-OLinuXino-7TS is used with same PCB and LIME stacked above it, no sharp edges, the laser cut is very clean these guys really know their job

    Nice boxes! Which software are you using for the design? Is it Open Source? The only OSS I have found for sheet metal bending is an addon to freecad. Do you know other?

    Now we have a perfect set-up for an industrial HMI! All we need now is to port Kivy to the A20-Lime/LCD and we have a winner! Kivy uses the frame buffer and OpenGL – does the A20-Lime Linux have openGL?
