I have found the C3 Supermini to be more than capable for every single project I tried. It is tiny, versatile, and most importantly, cheap! I keep 5 on hand at all times and order more when I run low. They are that good!
Huge shout out to the folks over at mischianti.org who provided the only pinout diagram which matched the C3's I use. Links to their extremely helpful site by clicking on the image below:
