$16 Raspberry Pi Case Integrates a 3.5″ Touchscreen Display

Most Raspberry Pi cases are not really newsworthy, but there’s an unnamed case for Raspberry Pi 2 & 3 boards sold for $15.99 on Banggood that looks like a normal case, except the top cover is replaces with a 3.5″ touchscreen display, and the kit also ships with a stylus.

Raspberry Pi Case Touchscreen DisplayKey features of the display:

  • LCD Type – TFT
  • LCD Interface – SPI
  • Touch Screen Type – Resistive
  • Touch Screen Controller – XPT2046
  • Colors – 65536
  • Backlight – LED
  • Resolution – 320×480 (Pixel)
  • Aspect Ratio – 8:5

There are two ways to assemble the kit. Either with the 3.5″ display and no fan, or without display, but a top cover including a fan. I’ve not sure why would anyone would purchase this kit without using the display but at least you know that’s an option.

Raspberry Pi 3 Resistive Touchscreen StylusThere are ready-to-use Raspbian images for Raspberry Pi 3 and Raspberry Pi 3 B+, but I doubt they’ll be updated, so instead, you may want to download Raspbian from Raspberry Pi website and install the driver yourself:


Some people had the wrong orientation for the touch control (X & Y inverted), but luckily there’s an easy fix requiring you to edit /etc/X11/xorg.conf.d/99-calibration.conf and add the line:

for using it in your applications, note that this a resistive display (requires using the stylus). Anyway, nice price.

Agreed, that’s a nice resolution for that size as well.

Another limitation to keep in mind is that it’s an SPI display so the update rate will be quite slow–guessing <10fps. So, don't expect to play videos or games on it. But for a status display or such, it would work great.

Most would be using it for status display anyhow…

Keep in mind that though it is resistive, that doesn’t typically mean other object input won’t work; just in this case, for any semblance of accuracy in a non-touch optimized application, you’re going to want to use a stylus!

Is it possible to control backlight ?
