GeeekPi2Pcs OLED Display Module I2C IIC 128X64 Pixel 0.96 Inch Display Module Yellow Blue Two-Color Display Compatible with Raspberry Pi Arduino 51 Series MCU STM32 R3 and Mega

It has fast boot up time, great product if you are using embedded c use an i2c library

These displays are truly small, yet are easy to read. Arduino software is readily available through the Arduino IDE. Im my case, I needed these for a Dr Duino course I was taking to create a Mini Weather Station with Digital Clock and Sunrise/Sunset. It was fun and affordable.

Works great with I2C and Adafruit Libraries -- #include <Adafruit_GFX.h>#include <Adafruit_SSD1306.h>. After a few setup lines, the display programming uses the familiar Arduino print( ) / println( ) commands.One curious problem solved was that it only seems to work with --#define SCREEN_ADDRESS 0x3C -- in spite of the library directions or the addresses printed on the back of the board. The yellow and blue pixels are not programmable colors. The top quarter of the screen is set as a type of banner with only yellow pixels while the bottom part is set with blue pixels.

I couldn't get this to work at first, then I used an I2C scanner and found it using 0x3c, which is the I'd for 128x32. 128x64 is 0x3d.I switched my settings to 128x32 and it works fine.Note that you need to set color to white to get the Adafruit library to display text. At size 1 you can only get 4 lines of text.

it works great

I had to do a pretty good hunt for code but once found I was able to use the LCD screen for my small RPi project. I like these and if I need more will certainly purchase.

I wanted an inexpensive way to track the state on my ESP32-C6 microcontroller during runtime. While it is small, it’s cheap and works great.

Lots of uses for these. They are not full multicolor, the top "line" is yellow, rest of the display is blue. Works very well unlike some of the other cheap displays on amazon.

It works like it should 👍

I connected one screen and it was lighting up then it stopped working. The second one the same thing. Do not waste your time buying this.
