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

Functional and as described.

This works great with my Gotek, but I do wish it was a little bigger

I wanted to use this for a solar-powered cloud-connected temp/humid meter. I've 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 it's not present, and nothing ever shows on the display. When I comment out the SSD1306 OLED code the sensor works fine. There's 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.

A pretty easy-to-use SSD1306, 128x32 resolution. I recommend playing around with the SSD1306 example in the Arduino library to learn how it works, it's pretty simple once you get the hang of it

works and functions perfect for adding a display to my pikvm. build quality seems good, size and brightness work well and is compatible with my pikvm and was a good value.

I don't 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, I'm sending these "Barbie and Ken" OLEDs back.

It does not come soldered with the sticks, it comes separate just as I need it

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 used this for a GOTEK unit that originally used a horrible numeric LED 7 segment display. I put the the flash floppy firmware on my gotek device and connected up this OLED display, which along with a couple of other mods makes the GOTEK so much more usable!

Two simple i2c displays running an SSD1306 controller. Particularly easy to interface with a Raspberry Pico ( there's an example code on GitHub ) and definitely worth buying.
