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

Excellent product

First, dont be fooled by the picture on the Amazon page -- these are TINY little displays. But, unlike other reviewers, I had NO problem powering this from my ESP32 3.3V power rail.

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.

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!

Concuerda con la descripcion, funcionan perfectamente.

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.

The first two worked. I havent tried the remaining.

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.

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.

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.
