Custom Raspberry Pi 4 case with 16x2 Display, Capacitive Touch and RGB LED









  •  I have been using Raspberry Pis for a long time now. Used many of the commercially available cases. RPis can be run headless (without a display) or an HDMI/SPI display can be used.
  • There are many cases that are available for the 5" displays, etc.
  • But it would definitely be nice to have small display with maybe an LED and touch support. Say like the commonly available 16x2 char displays and a WS2812B led and a button.
  • This led me to search for a similar thing on the Internet and finally to a ThingSurf.
  • Found this: Design on Printables webiste for a Raspberry PI 4  with displayThe Design is by user guytas on printables and already had all the things I needed.
  • This was locally printed on a Creality Ender.
  • The 16x2 display fit nicely. But as there was a need for an RGB did some "jugaad" and fitted an RGB Led below the button hole and a couple of capacitive sense buttons below the casing.
  • Wrote a small program to showcase all of the features.
  • The program shows the temperature of the Pi with yellow blinking and on button press moves over to blue and date and with another press to green with time.
  • It can be used for any kind of visual aid by means of the Display or the LED.
  • Need to check how it performs on long term use.
