Features: 100% brand new and high quality Comes completely pre-assembled and tested so you don't need to do anything but plug it in and install our Python code The PiOLED comes with a monochrome 128X32 OLED, with blue pixels. The OLED uses only the I2C pins so you have plenty of GPIO connections available for buttons, LEDs, sensors, etc. It's also nice and compact so it will fit into any case These displays are small, but very readable due to the high contrast of an OLED display. This screen is made of 128X32 individual blue OLED pixels and because the display makes its own light, no backlight is required. This reduces the power required to run the OLED and is why the display has such high contrast; we really like this miniature display for its crispness This mini OLED is design for Raspberry Pi computers, to give you a small display screen. We have a Python library for the SSD1306 chipset. using the Python imaging library. Our tests showed 30 FPS update rates so you can do animations or simple video. Works with any Raspberry Pi computer, including the original Pi 1, B+, Pi 2, Pi 3 and Pi Zero. Package Includes: 1 PC x Screen Display Module Specifications: Model; PiOLED I2C 0.91inch OLED Fit for : for RPI Raspberry Pi 1, B+, Pi 2, Pi 3 and Pi Zero Voltage: 3.3V Interface: IIC Color: Blue Dimensions: approx 35.0mm X20.0mm X10.5mm/1.38x0.79x0.41in note: Because of the resolution of the screen, the color may be a little different. There may be some errors in size due to the way of measurement.
