“It works, but the soldering is very fine work for the test point connections, and position is extremely sensitive.
Comes with *M3* plastic bolts (to prevent shearing movement) which can gum up when pushed through the holes (designed for M2.5) making the nuts hard to get on.
Metal nuts may be easier to use to counter the gumming, and both metal bolts and nuts might improve the long term robustness (but require some force get through the PCB's)”
“Easy to fit add-on to a Pi Xero. Yes, it needs a bit of careful soldering , but nothing too hard.
I was able to fit a 4 port USB hub board (from a different supplier - sorry) that connects via pogo pins on the the test points I had soldered to and it still works!
Next stage is the make a custom 3D printed enclosure and my plug in computer stick will be ready.”
