If you’re looking for a bright, readable OLED display for a Raspberry Pi (most likely a Pi Zero) project, this might be just the thing you need!
The Adafruit 2.23″ Monochrome OLED Bonnet for Raspberry Pi is your chonky OLED pal, ready to snap onto any and all Raspberry Pi computers, to give you a vivid display. The Bonnet comes with a 2.13″ diagonal monochrome 128×32 OLED, with sharp white pixels. The OLED the I2C pins plus GPIO #4 for reset, so you have plenty of GPIO connections available for buttons, LEDs, sensors, etc. It sits nice and flat so many cases that have an open top can have this display inserted.
Compared to our similar PiOLED display, this OLED has the same resolution but is much larger, so it can be read from across the room. This screen is made of 128×32 individual white 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 OLED display for their crispness!
Using the display is very easy, we have a Python library for the SSD1305 chipset. Our example code allows you to draw images, text, whatever you like, using the Python imaging library. Our tests showed 30 FPS update rates so you can do animations or simple video.
Comes completely pre-assembled and tested so you don’t need to do anything but plug it in and install our Python code! Works with any Raspberry Pi computer that has a 2×20 connector, such as the Pi B+, Pi 2, Pi 3, Pi 4, and Pi Zero (and any others that have a 2×20 connector!)
Please note that OLED displays are made of hundreds of…OLEDs! That means each pixel is a little organic LED, and if it’s kept on for over 1000 hours it’ll start to dim. If you want to keep the display uniformly bright, please turn off the display (set the pixels off) when it isn’t needed to keep them from dimming.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
