I'm a bit confused where the extra pads are for soldering/attaching additional dongles? I was wondering if there might be room for one of the kingston style micro sd readers, and where the pads would need to attach.

Also, I'm new to the PCB game and am not sure my youtube based know-how would enable me to assemble this. Before I attempt to order from JLCPCB, I was wondering if you had gotten enough interest for this to do a larger order?
