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

These things are quite nice, especially for the price. As you can see in the pictures, I created a snap-on bezel for mine to make for a cleaner prototyping experience (file available at thingiverse, search for thing 4768895). The AdaFruit SSD1306 Arduino driver works great for these modules. You can also control with any I2C device, if you read the datasheet for the SSD1306, available on the internet. Make sure the copy down the specs from the description (or print) and keep with the parts for future reference. You can power and control this from 3V3 or 5V due to the integrated regulator... quite nice.

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 saw others wonderinf about the address, it is 0x3d. Also I run it at 3.3 V directly powered from the board. No issues.

A bit smaller than I expected, but they are great little screens. Easy to read, and easy to use. Works perfect for displaying a little bar graph and some data.

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.

Terrible. Lacking headers, manual, and does not support 3v as it stated.

I attach them to a mkr 1010 shield between the headers and use the adafruit oled library. Photo of a well monitor attached. This has, wifi, a real time clock, a watch dog timer, an oled display and a SD card under the side of the display. It is also connected to a Blynk mobile app for monitoring and control. The oleds begin to dim after 6 months or so of use. Best practice is not to have them on all of the time. I plan on adding a small motion sensor that turns the display on or off. .

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.

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?).

not worth get something else trust
