5 Pieces I2C Display Module 0.91 Inch I2C OLED Display Module Blue I2C OLED Screen Driver DC 3.3V~5V(Blue Display Color)

Tested them with the Arduino sample sketches after downloading the corresponding libraries and they worked. 5 minutes from opening the package to getting something on screen.

The first two worked. I havent tried the remaining.

These are great value. Just be aware they are very small. Until you get one in your hand, its hard to convey how diminutive they are. Fortunately, they are very crisp and bright

These screens are very easy to use. Can not give full 5 stars since the I2C address is not configurable. Otherwise, these are a great addition to a project.

Not sure if the product was changed since some of the reviews, but the ones I got worked fine with IC2 and 3v3 on my Raspberry Pi. Also, mine came with headers, but I had to solder them myself. I prefer that, since it makes them a lot more flexible. Just be aware. To the person complaining about a lack of a manual - common man. Its a an electronics component, youre going to need to google your specific application. Thats true for basically every electronics component ive ever ordered.

I got exactly what I was expecting 5 very small i2c oled displays and 5 (4 pin breadboard pins). Very pleased with the product, bright, easy to work with and exactly what I needed! All those who complained about receiving tiny displays obviously didnt read the description. These are great for the new Raspberry Pi Pico! I havent received mine yet so Ill have to play around with my Raspberry Pi 4 for now.

3 were duds. 2 worked with ssd adafruit. Thanks to good comments here that led me to finding right drivers

Good displays - all set to 0x3C i2c address. Came without pin headers soldered, which was perfect since I needed a locking connector, not header pins. The headers are in the bag so if you want them just need to solder them on. I hope more white displays are in stock soon!

There is no documentation at all for these devices. It turns out that the Adafruit libraries work just fine IF you know that the IC2 address is 0x3C and change it in the examples. The brightness is just fine and they are quite cheap, but they are incredibly small.

Was a little nervous buying them reference the price, but took a chance. The silk screening was very nice. Nice bright blue for the board, and bright white for the lettering. Each OLED came with a header. They fit very tightly. Once I connected the headers with the board with out soldering, I was able to hold the board upside down by the headers and they did not come off. (still kind of new to this, so dont judge me), soldered at 433 soldered perfectly. No burning, warping, or discoloration on the board, the heasers did not melt (make sure you use flux, makes a world of difference. Nice bright images even in full light. Was kinda mad when I first saw the screens, they looked all messed up, but saw that there are screen protectors on them. Nice little touch for a cheep priced screen. Ill buy more just to have some laying around. I got them up and running 09/29/2021. Now lets see how long they last.
