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 speed 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.
If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.
Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

Nice and easy to use display showing status and sensor values of my robot. As I have been not sure how big or small the text is on the display I purchased also the bigger version of the display. Maybe it would be good to show a picture with text to get a better visual impression about text size.
The size of this display was perfect for my project and paired well with the other Qwiic modules. The display itself was very lightweight and easy to attach

I also came here to make the comment about putting the Qwiic connectors on the back. It was the first impression that I had about the board.
In fact, most boards that have sensors or anything that might need to be more accessible for mounting should have the Qwiic connectors on the backs of the boards...even the breakouts. Especially if the boards have mounting holes, it just makes more sense.
HA I came in here to make exactly the same comment as the fellow just below me an hour ago. Please consider moving the connectors to the back of the board in a future revision, or having 2 versions. Some of us do put projects into cases at least sometimes, and if not it really doesn’t matter if the connectors are on the back.
The only fault that I can find with this display is that the Qwiic connectors are on the front of the board. If they were on the back, it would be easy to mount the board with the display flush to the panel, instead of the Qwiic connectors being in the way.
