Continuing the glory of the Inkplate series, we present you the newest board - Inkplate 6COLOR - an incredibly simple to use e-paper display, now with colorful e-paper display. Powerful, Wi-Fi-enabled ESP32 microcontroller makes this 5.8" color e-paper display incredibly easy to control. Just plug in a USB cable, open Arduino IDE (or MicroPython), and change the contents of the screen with a few lines of code! Thanks to its low-power mode, you can run it for months, or even years, on a single battery. Our Inkplate series is everything you ever needed from an e-paper display, in a single ecosystem.

Making Complicated Technology Simple

Let’s face it, other e-paper displays are a hassle to work with. For one thing, they usually require additional hardware—breakout boards for connectors and cables, or external microcontrollers. And their documentation is often pretty rough, with few examples and little or no sample code. You can make them work, sure, but it takes a lot of effort, and most of us just don’t have the time and resources to go that extra mile.

This is where the Inkplate comes in. Designed with simplicity in mind, it addresses all of the challenges that e-paper brings with it. Let’s start with hardware: everything is plug-and-play; just connect a USB Type-C cable, press the power button, and you’re ready to go. Inkplate boards contain all of the bits and pieces you need to get started, including a Wi-Fi microcontroller, microSD slot, extra input/output pins, Real Time Clock (RTC), Li-ion battery charger, and more. As for the screen, Inkplate 6COLOR has a slower refresh time compared to other Inkplate boards, but it compensates for that with a beautiful multicolor screen. You can show a total of seven different colors or use built-in dithering algorithms for even more realistic colors renderings on the screen.

Inkplate has you covered on the software side, as well. If you’re the Arduino type, you’ll have text on your screen in less than five minutes. Install the board definition, download the library, and open one of the many sample applications. Customizing those samples is about as easy as it gets. Using a library based on the Adafruit GFX graphics library, you can add text, images, and other graphical objects to the screen with just a few lines of code. The full documentation is here to help you finish your projects. MicroPython module and sample code will be provided as well.

In fact, our obsession with simplicity goes beyond the hardware and the software. Want to make your Inkplate look stylish and keep it safe at the same time? We’ll save you some time (and some filament) by pre-installing your board into a custom, 3D-printed enclosure.

E-Paper Looks Like Magic

There’s just something about e-paper displays. We find e-paper fascinating for a number of reasons, but let’s start with some facts: it just looks brilliant, uses power only when refreshing, and it has no glare. Now, after being so used to black & white e-paper displays on e-book readers, let us surprise you with the actual color pixels. The AC057TC1 e-paper screen from E-Ink Corporation packs seven color pixels for each physical pixel on the screen, and by dithering them, you can show real masterpieces on its screen.

Some "screenshots" of the e-paper on Inkplate 6COLOR

Technical specs of the screen:

• A 5.8-inch, 600 x 448 pixel color e-paper display, with the active area of 114.9 mm x 85.8 mm
• Seven colors directly available (Black, White, Red, Yellow, Blue, Green, Orange)
• SPI communication
• Dithering algorithms built into the Arduino library, so you can show any color using the seven existing colors
• 128 DPI (Dots Per Inch)
• the manufacturer datasheet specifies a 25 second refresh time, but our real-life observed refresh time is 10-11 seconds

What Can I Use Inkplate 6COLOR For?

• A high-latency information panel - Show calendar, temperature, weather, and air quality data. Track your stocks, learn a new word each day, display information about whatever song is playing, or keep tabs on your social media accounts. Switch between various options easily using the touchscreen. Inkplate 6PLUS will draw almost no power until it needs to pull new data or refresh its screen.
• A collaborative task tracker - Maintain shared lists of groceries to buy, chores to do, and birthdays to remember. No dry-erase markers required - just tap the screen to mark as done. Or, replace the power-hungry wall monitor in your office with an e-paper task display on each desk.
• An open hardware e-reader - Sweep aside the barriers put in place by restrictive, centralized platforms, and e-read whatever you want!
• Art - Frame photographs pulled from an SD card or an online camera roll. Or generate abstract art from sensor data. Or torment your house guests with a modern take on the "photo booth". 6COLOR is the perfect platform for showcasing artwork.
