128x64 graphic OLED display


In my microcontroller projects I often use various means of displaying information. Often these are 7-segment indicators or symbolic LCD displays that hardly satisfy the needs of my wild fantasy due to the limited ability to display graphics, etc. Once again, turning over products on the site Aliexpress, I came across a solution to my problems, namely a graphic oled-display with a resolution 128x64 dots and small sizes - total 0,96 inches. Although the visible area of ​​the screen is 25x15mm, I was pleasantly surprised by the image quality and readability of the text (even with a very small print).

To work with the display, four contacts are displayed in its upper part (from left to right): GND, Vdd, SCK, SDA. Contacts GND and Vdd designed to power the display voltage 3.3V - 5V. conclusions SCK and SDA serve to connect it to I2C bus data. This is another plus of the screen, since it is controlled by only two wires, which significantly saves the outputs of the microcontroller. Platform lovers Arduino a pleasant surprise awaits - an excellent library has been developed for this display u8glib, which greatly facilitates the acquaintance with him.

Summing up, we can say that the small size, together with the sharpness of the image, high speed and ease of control, undoubtedly bring this Chinese miracle of technology to a leading position in comparison with its liquid crystal counterparts.

Cost: ~ 130
