Display-O-Tron HAT
by Pimoroni
Great for including a colourful character display and button inputs on your Raspberry Pi based projects!
Includes a 16x3 character LCD display, 6-zone RGB LED backlight, bar graph, and six capacitive touch buttons all in one slim package.
It's ideal for controlling your internet radio or home automation projects.
Features
- 16x3 character LCD display (full ASCII character set and eight custom glyphs)
- Fully controllable six zone RGB backlight
- Six bright white bar graph LEDs (individually dimmable)
- Six capacitive touch buttons
- Power, I2C, SPI, UART, PWM, and five GPIO pins broken out
- SN3218 LED matrix driver chip (drives the RGB backlight)
- Microchip CAP1166 capacitive touch driver chip
- Display-O-Tron HAT pinout
- Compatible with all 40-pin header Raspberry Pi models
- Python library
- Comes fully assembled (breakout pins require soldering)
Software
Our Display-O-Tron Python library will get you going in a jiffy, and makes controlling Display-O-Tron HAT really easy.
We've included examples showing you how to use the backlight, bar graph LEDs, and touch buttons, as well as more advanced examples showing you how to create menus, games and even an internet radio!
Notes
If you want to keep your Pi in a case, we recommend the Pibow Coupé case as it will allow you to still use the capacitive touch buttons.

Great solution if you're stacking a bunch of hats like I'm using it for, great quality screen and easy to code with too.

love it. the screen would need a bit more protection.
very useful to show short logs, or use colors as info/warning/error hints ;-)

Wonderfully retro and everything in package! Soldered a 90-degree header on it, and I have an office air quality station now. Red backlight means open the window and can be seen from far away; thresholds are customizable with the buttons, etc.

This is absolutely ideal for my project. It's easy to use and works flawlessly. The screen is bright and crisp and fully legible in bright sunlight.

Bought to replace an older "Display-o-Tron 3000" for a project where convenient access to extra GPIOs was required.
The extra backlight LEDs in the dotHAT (over the dot3k) makes the display better in the dark.
The capacative keys work well, although the screen gets in the way of accessing the [up] and [down] pads which are immediately to the left of the display.

Excellent bit of kit for tinkering. I used the DOT Hat to control the Phillips Hue Lighting system at home. Currently looking to move the project to run on a Pi Zero and build a custom case for it.

Great little display, even better is the ongoing support and python library! :D
With a little tinkering I turned it into an airplay music visualiser:

Fantastic device, the ability to be able to set the 6 individual zones of the LCD to different colours is really useful, also the built in white bar-graph is insanely bright which is really useful. My only comment would be that the touch-sensitive buttons are a little close to the edge, a bit more space around them would be handy for the fat-fingered amongst us.

Awesome product, helps you to get started with python. Also, as it's Christmas, I thought I would make a Santa tracker! here is the GitHub link if you like: https://github.com/appledeej/DisplayotronHAT-Santa-Tracker

Very good quality display, I use it as a clock and i'm planning to add social media stats! Super bright LED's and really good resistive buttons, worth every bit.

Although my needs are quite modest there's oodles of functionality here which makes the DotHAT extremely versatile. I'm also very impressed with the documentation and the breadth of programming examples which illustrate the capabilities very nicely.
I'm using it as a control panel in a maker project - you can read the blog post I wrote about this aspect of the build here: https://pleasereleaseme.net/build-raspberry-pi-vehicle-interior-monitor-screen-test.

Simple and easy control and interaction with your project. Can be set up as a local controlpanel. Background colour can be used to indicate status of program/system. Clear textmessages you can set up for yourself.
