I haven’t mine opened up yet. How much space is there up top where the plastic space in case is ?
Thinking of installing a small 5 GHz WiFi module to this spare USB header.
You can get pretty small USB ones and if broken down to remove case and USB plug, i’m guessing the PCB in these would be tiny enough to slip in somewhere and wire directly to this header.
Inbuilt 2.4 GHz basically renders Bluetooth useless due to interference, so WiFi at 5 GHz would be good mod if feasible.
But for best signal, it would be need to be up top in plastic section to get through shielded case.
