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

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.

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.

Simple, 4-wire, I2C OLED display. Bright graphics and text.

Look at the amazon picture, the screen doesnt display anything below the VCC pin. I have seen this on my display and tried to address to 40/48/64 to try and fill some of the unused space but it doesnt show.

i havent had a chance to put these into a project yet but i tested one for fun and it worked just fine.

No issues getting it setup, worked immediately.

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.

Both boards doa

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

I wanted to use this for a solar-powered cloud-connected temp/humid meter. Ive made a few of these already. However this display would not work with the SHT40 sensor. The sensor and display both sit on the I2C bus and you should be able to connect up to 127 devices on the I2C bus, but when I add the standard SSD1306 OLED code from the example in the Arduino IDE, the MCU can no longer see the SHT40 sensor, says its not present, and nothing ever shows on the display. When I comment out the SSD1306 OLED code the sensor works fine. Theres no I2C address printed on this display and no mention of one in the description. I tried the standard one of 0x3c and also 0x3d but got nothing. Have never seen the display light up at all, not even the splash screen.
