Recall this sale from last week
Well I had a 62447, and it is the most hackable of the three I have. This 61910 is good too but the signal pin is really hard to solder.
I hope to get a 69590 as well to have all four and with images.
The first one I played with, the 93068 doesn’t seem as hackable, but is usable because it is easy to solder. It is just that you have to use separate power supplies.
