Display-O-Tron HAT - 16x3 Character LCD Display for Your Raspberry Pi

This LCD display is so much more practical than the other ones that go on a breadboard or have to be assembled. Takes 5 seconds to install and it comes with very nice libraries to program. I use it to display IP address and other items from my Pi.There are a few drawbacks. The contrast is not the best, but if you play with the colors and contrast parameters you can make it readable. I found that contrast of 50 and RGB of 0,200,0 (green) is the most readable.The second potential drawback is that there is no GPIO passthrough connectors, so this needs to be on the top. If you plug this directly to Pi GPIO then you can't plug anything else there. But it makes for a very nice, low profile Pi with a display. (see pictures).Note that the more common cases don't have enough room to plug this display, you need to get some of the more low profile cases.See pictures. Overall, highly recommend it you are looking for the fastest, easiest way to plug an LCD display to your Pi. excellent value, very robust.

Great hat. Good sample software too.I used this to build a scoreboard for our foosball table!
