Frienda 2 Pieces I2C OLED Display Module, 0.91 Inch I2C OLED Screen Driver, Compatible with Arduino, Power-Saving, Self-Illuminating, 3.3V - 5V(White Light)

Functional and as described.

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 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.

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

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 have purchased many of these and they've 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). I'd but them again, but they are laying all over the place already. I can't put down my coffee without moving one of these first.

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

works well

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!
