Did anyone made replacement expansion boards that would slot on the side connector? The speakers are mostly useless so removing that side board that is basically empty, could open up the bus to the other IO on the device. I saw some people soldering wires on the PCB to get an extra USB port but I would rather get something like an alternative PCB if anyone has some open source posted on github.
An extra USB is nice, but mostly I think there is more to gain by having that space open for other things.
