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

No surprise. Work and perform without issue.

Excellent product

First, dont be fooled by the picture on the Amazon page -- these are TINY little displays. But, unlike other reviewers, I had NO problem powering this from my ESP32 3.3V power rail.

Tested them with the Arduino sample sketches after downloading the corresponding libraries and they worked. 5 minutes from opening the package to getting something on screen.

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

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.

not worth get something else trust

Concuerda con la descripcion, funcionan perfectamente.

I use these with TinyPico boards using MicroPython, and they work great. The screen is bright, very responsive, and perfectly readable. It’s easy to display animations on it without it lagging. You can write text or control it per pixel, draw lines or rectangles, fill areas, and scroll. Im using these with the MicroPython library found at stlehmann/micropython-ssd1306 on GitHub. Theres also an Arduino library named ssd1306. Im glad to have found these at such a low price! A similar screen is available at Adafruit with the same dimensions, same SSD1306 driver chip, but with SPI communication instead of the more convenient I2C. They sell it at $17.50 for just one screen, more money than for *five* of them here. Im going to add those to most of my projects now, this is a much better way to display whats going on than using blinking LEDs.
