Didj vs LX cart diferences

looks like the pad thickness has changed from the didj to the lx

Maybe to reduce to the cost per board? Less surface area to plate?

sd pins and cart detect have longer pads now?

before this was only for the power pads

Pad size comparison, same magnification used on the microscope and angle

Arduino Enclosure Modding

Before:

Notice how the surface isn’t smooth with the plates in.

After:


How did I do that?
First I used a layer of plastic model glue to secure the panels in place. Once the glue had dried I sanded as much as i could to make the panels flat with the case surface. first with course sand paper 40 grit then move my way up slowly to 250 grit.
Next I applied a layer of primer paint. let it dry then sanded it down with 250 again.I then applied some epoxy to the cracks with a razor blade to make sure that the surface was as smooth as possible. sanded smooth then applied another layer of primer. once the primer was dried for a day i took some very fine wet sand paper and wet sanded the case till it was super smooth.
now it looks like there were never panels to begin with :)
