ALMOCN 0.91 Inch IIC OLED Display Module I2C SSD 1306 LED 128X32 Screen Driver DC 3.3V~5V (2pcs unsoldered Blue)

I like keeping these on hand for future projects. However, I'm not very good at testing electronics when they first arrive. I put them away. Then, when I need one, I find they don't work. When these displays arrived today, I tested each one. All four worked like a charm!

The only upside is that the screens I received were operational. The screens came with headers presoldered but in ripped open anti static bags. The soldering on the headers was the worst quality soldering I've ever seen and one of the headers were soldered onto the incorrect side of the PCB. I had to clip both headers off and resolder in new ones.I think I might have gotten a returned item. Usually these come with a protective film from the factory but there were none on these screens. I was supposed to get two screens that did not have the headers soldered on. I think someone purchased these, did a poor job soldering them and soldered the headers in the incorrect orientation and returned them.

Added these to my lily58 split build and they work perfectly. No issues with install and not very sensitive to heat as they were soldered in at about 280 C

good value. worked flawlessly in my project. will definitely reorder.
