Which uSD card socket was used in the design? I had a similar one but I can't get it to work so need to order the right one.

Are you sure? yes | no

Is there a schematic anywhere please? I just get no VGA out of my build and I'm trying to figure out why.

Are you sure? yes | no

hello, is there not a capacitor on the back of the sd card reader?

100 nF 250 V 0805 ?

Are you sure? yes | no

Working without, you can add lower voltage capacitor

Are you sure? yes | no

Oh at first glance it looked to me that the computer graphic at cover PCB had one of those tiny 128x96 OLED displays , lol!

Are you sure? yes | no

Cool form factor you have created, with the keyboard and cover layer. It should work nicely for a Zero W too.

Are you sure? yes | no
