2.23 inch OLED Display HAT for Raspberry Pi 2B/3B/4B/Zero/Zero W Jetson Nano 128×32 Pixels SPI/I2C Interface

Bought this for a raspberry pi project. Worked perfectly and I had no issues getting it setup. Very bright and crisp display.

I used this to create a clock using a Raspberry pi zero. Works great!

This product worked well, but I had issues with setting it up. I had to load an old version of Rasbian that didn't have the Linux 5 kernel then lock the kernel package and upgrade all other packages to get the python library provided by the manufacturer to work. Despite the setup, the display itself is easy to program.

Fits and looks good, perfect size for status updates on a pi zero.

Works great 👍

This is either the weirdest malfunction I've seen yet or this is not compatible with the oled node in node red.

Programming this little screen is fun, but the resolution is too low for anything really useful and there's no input, so save this for something like a small ticker or something.

I've left this device in the default SPI mode, though I may reconfigure for I2C to recover some GPIO pins that will find use for other purposes, but I love that this OLED supports either method of addressing.Modifying the sample scripts was not hard, though to prevent screen "burn-in", I added timeouts to re-blank the screen after so many seconds, and a "trap" to re-blank in the event a script dies or the process is killed.A nice product. Be mindful the glass is thin, and will break if you "mash" it onto your GPIO header.UPDATE: When I first bought this, I was running Stretch, and Buster. I'm now running Bullseye. Bullseye ships with Python version 3.9.x which required modification of my scripts, when printing text to the OLED display. Specifically, I added "import codecs", and each variable that I wanted to display now requires a call to "codecs.decode()", due to the way Python 3.9 handles strings.
