In summary, this kit is a great demonstration of how far e-ink technology has come in recent years. It’s not just about the six native colors, but also about what can be achieved by playing with patterns and color blending. The combination of the ESP32-S3 with the Spectra 6 display offers plenty of room for experimentation: ranging from information panels to more elaborate interfaces that take advantage of the low power consumption and the unique aesthetic of ePaper.
Throughout this post, I’ve highlighted what truly matters when working with these displays: color behavior, limitations, which combinations work best, and what to expect from the refresh rate. These are the details that make all the difference when you start designing icons, layouts, or dashboards that actually look good.
Ultimately, this kit is an excellent foundation for anyone looking to tinker with ePaper without getting bogged down in complexity. It allows you to learn, test ideas, and better understand how these multicolor panels function. Above all, it opens the door to projects that can look visually stunning if you play to the screen’s strengths.
What do you think of the results? The theory is clear, but practice is where it gets interesting. In my next post, I will explain how to convert images into arrays and display them as efficiently as possible. It’s a process with its own set of tricks, especially regarding multicolor ePaper, so I’ll break it down step-by-step so anyone can implement it easily.
