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

I got exactly what I was expecting 5 very small i2c oled displays and 5 (4 pin breadboard pins). Very pleased with the product, bright, easy to work with and exactly what I needed! All those who complained about receiving tiny displays obviously didnt read the description. These are great for the new Raspberry Pi Pico! I havent received mine yet so Ill have to play around with my Raspberry Pi 4 for now.

These are nice displays but easily broken. There is no easy way to mount them and the glass is easily broken.

I have been trying to make this work without luck. Seems device is detected (in 0x3C address) but no text/backlight on screen. Tested the 5, same result ....... maybe I am missing something (Will update in case this works). ———————————————- UPDATE: I used Adafruit library and all screens work flawesly, really happy with results

The first two worked. I havent tried the remaining.

Would have give 5 but one of them was cracked.

Is a copy of an Adafruit display and the Adafuit libs for Arduino work with this device. Just note, this is a very very tiny display. For reference the pins are 2.54mm pitch. Cant beat the price for what you get. Just note that I2C is slower than SPI, or high speed parallel so the refresh rate is low, but its still pretty quick.

I attach them to a mkr 1010 shield between the headers and use the adafruit oled library. Photo of a well monitor attached. This has, wifi, a real time clock, a watch dog timer, an oled display and a SD card under the side of the display. It is also connected to a Blynk mobile app for monitoring and control. The oleds begin to dim after 6 months or so of use. Best practice is not to have them on all of the time. I plan on adding a small motion sensor that turns the display on or off. .

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.

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

Excellent product
