0.42 inch OLED Display Module (72x40, SSD1306, I2C/SPI) (102122)

This 0.42inch OLED might be the smallest OLED display in the world. It can display up to 10 text in a row, and 5 lines text. The display size is smaller than a laptop keypad. So it could really open our mind to create some cool things that we could never imagine.

We are offering two different interface modules, SPI and I2C, you can pick a suitable one for your preference. We can also offer you bare display, so it can be embedded into even smaller space, and if you need a RnD support for your project, please contact us.
