This is a well-connected motherboard; to get it free, we pop off the digitizer, backlight, and speaker connectors, two antennas, and the two Joy-Con rails. And then remove six Phillips screws.

But hey, that's some awesome modularity. Even the eMMC storage pops off with an independent PCB!

Nintendo made a 6.2" tablet with removable flash storage, so don't say it can't be done.

The storage board contains a single Toshiba THGBMHG8C2LBAIL 32 GB eMMC NAND Flash IC.

Sadly, the modularity ends at the USB-C port. This high-wear component will require some intense soldering skills to replace.
