      @hondanhon It's Ultra Thin. It has pins on all four sides. (Quad) It's flat. It has no leads. That last one is what makes the thing I need to do harder. I'm crap at soldering and need to attach a wire to a little patch of tinned copper 0.22mm by 0.4mm or so

    @hondanhon My microscope does have USB video out, but now is not the time for me to start streaming to twitch.

      @hondanhon Step 1: make sure I have wire small enough.

        @hondanhon Not exactly my best work, but it works!

          @hondanhon I actually had it working quite a bit earlier, but tried to clean up one of the solder joints and ripped the pad off the PCB. So I ended up needing to bond to the tiny sliver of exposed pin on the chip. and then I just drenched the whole thing in super glue.

        @hondanhon Step 2: Find a sacrificial board with similar pitch to practice on, instead of one of the only four current prototypes of the Model 100.

          @hondanhon Say a slightly busted board from a previous design rev.

            @hondanhon So far so good on the sacrificial test board.
