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

Worked well. The example code in Arduino IDE for the Adafruit SSD1306 Library worked and provided a start.

This will work nicely if I stack my pis in a cluster, since the height is about what Id have between pis anyway. Took a bit of fiddling to get the adafruit library to install, and as you can see in the image some extra control characters display from the example, but when I use it Ill make sure the text is more relevant to what I want. I had to turn down the contract on the picture because its a bright little thing, and was washing out the picture otherwise. I didnt mind not having the headers installed. While headers are nice at this breadboard stage, the other three I may solder wires to, and just have them end in plugs I can attach to the i2c bus. I think it makes sense for a bulk seller like this to omit the headers. Finding the address was trivial, but I couldnt find the manual referenced in the description. Turned out a few minutes on google got me the right instructions for a Pi though. Thats the great thing about the pi is the community support. Id be happy to buy them again if I found a need for more than 5 (cluster expansion maybe?).

I received these two days ago. The order was filled very quickly and the packaging was very good. There was no visible damage to the box and the displays were wrapped in bubble wrap. Unfortunately only two of the five displays worked. The first display I tried would not work and I tried another and it worked. I contacted Amazon after I completed the testing and explained the problem. The agent I chatted (Crystal) with was very professional and agreed to send out a replacement of another 5 displays. The replacements arrived the next day. Unfortunately only two of the five replacements worked. I now have 10 displays but only four are functional. Very disappointing. The service from Amazon was outstanding. The product is very disappointing and I would not recommend.

No surprise. Work and perform without issue.

If you have been working with the other 0.91 square OLED modules, it is reasonable that these advertised 0.91 OLEDs would be at least the same size. WRONG, they are HALF size. False advertising and a real rip-off. I suggest you dont buy these.

ill admit i didnt pay attention to the size in the description, they looked much larger in the photos especially for what they were displaying on the example. however they are about the size of a fingernail. not much use i can get out of them but ill keep them since they were cheap

Is a copy of an Adafruit display and the Adafuit libs for Arduino work with this device. Just note, this is a very very tiny display. For reference the pins are 2.54mm pitch. Cant beat the price for what you get. Just note that I2C is slower than SPI, or high speed parallel so the refresh rate is low, but its still pretty quick.

Excellent product

This I2C Display Module work with no problems for the Arduino project I was working on. I personally like the Blue color LED it was easier for myself to read in any of the lighted conditions I was using this module in. There is plenty of online help and libraries for this unit just make sure you have the correct numbers for this display module when searching.

Good quality for the money, easy to use with ‘ssd1306.py’ driver for MicroPython code Works well with Raspberry Pico using Thonny IDE
