The Oled 1.3" I2C SH1106 display has a resolution of 128*64 pixels, allowing you to control each pixel individually and display both text and graphics. In addition, because it is of OLED type, it does not need backlighting like LCDs, which makes its energy consumption much lower and increases its contrast.
The display has an I2C type communication interface. Designed to work at 5V directly thanks to its on-board voltage regulator and can work with 3.3V or 5V systems without the need for converters.
