Customer evaluation for "Plaid-Pad 4x4 Macro Pad / Numpad"

Very enjoyable first build. the guide helps not to feel too lost

I really enjoyed the build. Everything is pretty well labeled, or if it's not labeled, then there is no confusion (thinking about the Zhener diodes, that are not labeled but only have the symbol)

The wiki page guides you well, but I felt a bit lost when I reached the switch soldering.
All my switches only had 3 "prongs" (feet?) and as a result, the keys are a bit wonky and not that well aligned.
I suppose that's why there are switches with 5 prongs, to keep them well aligned.
I am not complaining that it's not indicated on the shop page, but a simple "recommended" link to switches could have cleared the case, especially for a beginner.

Also, the USB C gave me some difficulties, but bad eyesight and shaky hands didn't helped.
I would have liked the option to use a full Arduino with an already soldered USB port.
My usual soldering iron (ts100) was way to wide to solder that... I had to find an iron with a smaller tip, and I was unsure if I had a short circuit, but as I could not remove it, I tried to power the keypad and it was ok.
So, it looks like there are traces between the left and right most pins to the ground.

I am now looking how to flash a custom qmk firmware, as I want to have a second layer and some macros available.
I still haven't found how, that's unfortunate that the wiki doesn't cover that part.
It's like the reset / boot button. Reset I understand, but what purpose the boot button have?
It's a mystery for me.
