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

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

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.

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.

Great price per module and all five displays worked properly. However, the modules and 4-pin headers were all placed in a single bubble-wrap bag, then inside a small box. Individual ESD bags for each module would insure the modules did not rub against each other during shipping.

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.

Would have give 5 but one of them was cracked.

I am using an ESP8266 with ESPHome. This was very easy to wire up and configure. ESPHome has great documentation on their website on how to setup font sizes, and to write values/images.

These are nice displays but easily broken. There is no easy way to mount them and the glass is easily broken.

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

I use these with TinyPico boards using MicroPython, and they work great. The screen is bright, very responsive, and perfectly readable. It’s easy to display animations on it without it lagging. You can write text or control it per pixel, draw lines or rectangles, fill areas, and scroll. Im using these with the MicroPython library found at stlehmann/micropython-ssd1306 on GitHub. Theres also an Arduino library named ssd1306. Im glad to have found these at such a low price! A similar screen is available at Adafruit with the same dimensions, same SSD1306 driver chip, but with SPI communication instead of the more convenient I2C. They sell it at $17.50 for just one screen, more money than for *five* of them here. Im going to add those to most of my projects now, this is a much better way to display whats going on than using blinking LEDs.
