This OLED Display from Zio can display up to 3 lines of text and features 128x32 pixels in a small 0.91” (diagonal) frame. As an OLED, this display does not have a backlight layer (unlike LCDs) and therefore it’s thinner, consumes less power, and has higher contrast.
Additionally, The firmware is optimized to update only the part of the screen that changes rather than transferring information for every single pixel during each screen update so ppeed isn’t compromised however, thanks to this I2C command structure. This is the same concept use with "Dirty Rectangles" or "Bit blit" operations in computer graphics.
The breakout board also features 4 mounting holes that can be snapped off and 2 Qwiic connectors to allow for quick and easy daisy-chaining.
The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.
