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.

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.

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

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.

This is an awesome, tiny, high resolution OLED for any of your micro controller projects. It used the very common I2C bus, and runs on the SSD1306 display driver. 128x32 pixels gives you a nice sharp, crisp text output. Im very happy with these. This is a really good way to add a very compact LCD to your project. No need to add some big bulky backlit LED, go with this instead! I used the Adafruit SSD 1306 Libraries and they worked great. They are low power and bright. For the adafruit library examples, they really are over the top. There is no hello world essentially, so just do a google search for a hello world example for the libraries to get a basic starting point. Also, to rotate the display 180 Degrees, put in display. setRotation(2); in the setup. Basic usage for those libraries are.. display. display() ; display. clearDisplay() ; display. setTexSize(1-3) ; display. setCursor(0,0) ; // origin of text display. print(blah) display.println(-appended to last word blah, then new line ) ; As for the hardware, the displays are nice and small. If you think of your breadboard, they are 4 rows high, then about 12 slots wide. (Thats the entire board.) Voltage range is impressive and seems to operate at lower than 3.3, but Im running it on 4.5V and there are no problems. (Basically, 5v from the wall but through a diode on the arduino). It takes around 5ma. With a watch dog timer and adjustment I bet you could I get a whole pro mini project to run at under 3ma standby while keeping the display going. Refresh time on the display is very fast and cameras dont pick up any multiplexing/flicker. They did not come with headers, but the plated through holes are very well done and take solder well. The holes are pretty snug, which means its strong. It will be hard to desolder these after , so google some tricks on removing header pins to make your life easier!

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

Would have give 5 but one of them was cracked.

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.

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.
