Hello!
I saw a long time ago on this forum someone who had added an internal USB port to add an SDR or a Wifi key close to the batteries. It was soldered to the sound module which is on the side (which could be LTE). I bought this soldering iron, but I can no longer find the images of what to solder to put my USB dongle inside the console… does anyone remember that?
I remember an even older thread with pictures but this came up with a quick forum search.
