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

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

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.

I think these will work well, but Ive not seen any info telling me what the I2C address is for the module... any information anyone can share ?

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

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.

there are no headers soldered to the boards. i had to go out in the rain to get headers for $12 to solder them myself which adds about 80% costs to the item. there is also no manual for this product. the product is supposed to support 3.3v to 5v as claimed in title, but in fact it only supports 5v. i wasted a couple hours to find this out. the product works but it is very inconvenient to make it work.

If you need a small display for your Seeed Studios, Adafruit, or Arduino Microcontroller or Raspberry Pi / Pico, this one is bright, 3v3 compatible, and easily driven with i2c using an SSD1306 library for Arduino/C or CircuitPython. 128x32 is enough to get four small lines of text for status reports or messages. I powered these with a Seeed Studio Xiao. I used the Adafruit Library. So compact you could make a wearable name-tag or display.

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

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.
