Unit OLED

SKU:U119

Description

Unit OLED is a 1.3-inch OLED expansion screen unit. It uses the SH1107 driver solution, supports black/white display, and has a resolution of 128 x 64. The driver chip uses the I2C communication interface, allowing users to connect it to the I2C bus of existing devices, saving IO resources. The back of the screen features a magnetic design, making it easy to attach to metal surfaces for fixation. This OLED expansion screen is suitable for embedding into various instruments or control devices that require simple content display as a display panel.
