2 Pieces I2C Display Module 0.91 Inch I2C OLED Display Module I2C OLED Screen Driver 3.3V - 5V (White Light)

I dont know what our Chinese friends were trying to accomplish by claiming that these devices were 0.91 inches in height, when in fact they measure only 0.47. These things are tiny! The whole display is just slightly over an inch wide. Because I would prefer not to have to use a magnifying glass when looking at my instrument displays, Im sending these Barbie and Ken OLEDs back.

Both boards doa

I have purchased many of these and theyve all worked fine. Adafruit and seedstudio libraries work fine on these in arduino ide, so they are easy to code for and only take up 2 pins (other than power and ground). Id but them again, but they are laying all over the place already. I cant put down my coffee without moving one of these first.

These might be good for some project but I was surprised how small they were. I should have paid more attention to others reporting the same thing. I feel like the pictures mislead me into thinking they were larger.

Bought this to use as a display for a BBC Micro:bit GPS beacon project. I am using the Arduino IDE and Adafruit SSD1306 & GFX libraries. The i2c address which matches what the Adafruit libraries assume. I have not had a chance to use these in full sun, but they look really bright. Super happy with the product.

Very deceptive listing. These displays are smaller than a quarter. I was very disappointed and quickly returned these useless displays I was tricked into buying with misrepresented images. The downside of buying products online.

After about 2 days I went back to my project the screen no longer worked . So I installed other and it has been working fine for over a week.

Had a good time configuring it for my electronic projects

Pretty easy to get screen up and going. I2C address was 0x3C. I have tested 1 screen so far and overall the product does what I need. However buyers should be aware of the following: -32 x 128 pixels are not in center of glass screen. (picture 1: all pixels lit) -Pixels do not go to the edge of the glass. (picture 1) -Pixels in the top two rows appear to light up when pixels on the 3rd row are lit (picture 2). Current Draw: - based off some measurements I took with a cheap DMM: --All pixies off current = 4.9 mA --All pixles on current = 27.5 mA --Current (mA) = (Percent of pixles lit / 100%) * 22.6mA + 4.9mA Frame Rate (with adafruit library): -max frame rate with 400khz I2C: ~73fps -max frame rate with 800khz I2C: ~130fps
