Here’s a simple minimal kicad project skeleton for customizing uConsole expansion boards. The dimensions are either measured from the 4G expansion board or traced from the mechanical drawing.
The pads for speakers are the same size of the 4G board’s, and their locations are verified with real hardware. However, I do not guarantee that everything will work the same way with the manufacturer of your choice.

I publish this to empower others, avoiding duplicated effort. I really don’t want to waste it on a one-time project.
Have fun tinkering! ٩( ᐛ )و
