“I like the micro dot pHAT as it works really well with these light matrix Pimoroni sells. I tried out the example code and was able to get things working in quick order without much issue. Soldering wasn't too bad albeit there were a lot of pins to solder in this full set so be aware you have some work ahead of you.
I'd consider using these for future projects where I need to show off a counter of some form as it really gives a neat effect. Would recommend.”
