I like ChipworkX. I have researching similar units and I think ChipworkX is the best.
The only thing I would have changed about it, is the layout. Basically two main items (see the attached image):
- change orientation and location of the IO pin header
- move all top connectors to the bottom.
I always find it awkward to hold somethings with wires running from the top. If you hold unit vertically wires pull the top of the unit down. Moving connectors down will allow to move main header to the top and orient it horizontally. I would like to make a case for it where the header is exposed at the top,so I can mount custom designed modules - “add-ons” for the unit.
Moving screen a little bit higher will make it easier for people with big thumbs trying to press “left” button without interfering with the touch screen.
I don’t have the unit myself yet, so this is just my observations based on the product page.
