🔲 2.23" OLED Display HAT for Raspberry Pi 2B/3B/4B/Zero/Zero W Jetson Nano, 128x32 Pixels, SPI/I2C Interface by XYGStudy Review

Through trial and error, I found that this single board computer was almost impossible to set up properly. The documentation provided was confusing and unhelpful, and the interface was clunky and unintuitive. However, the board itself was reliable and fast once I managed to get it up and running.

I left this device in standard SPI mode, although I can reconfigure it for I2C to add some GPIO -Restore pins that will be used for other purposes, but I like that this OLED screen supports any addressing method. Modifying the example scripts wasn't difficult, although to prevent screen burn-in I added timeouts to re-blank the screen after that many seconds and a "trap" to re-blank when the script dies or the process terminates. A good product. Note that the glass is thin and will break if you…

This product worked well but I had some issues with setup. I had to get an old version from Rasbian, which didn't have a Linux 5 kernel, then lock the kernel package and update all other packages to make the vendor-supplied Python library work.Although the display is customizable, it's easy to program.
