Versatile, easy-to-use, Wi-Fi-enabled e-paper display
A powerful, Wi-Fi enabled ESP32 microcontroller makes this six-inch e-paper display – recycled from a Kindle e-reader – incredibly easy to control. Just plug in a USB cable, open Arduino IDE, and change the contents of the screen with few lines of code.
E is for Easy
With Inkplate 6, the goal is to make e-paper accessible to hobbyists and DIY product designers by offering a plug-and-play hardware platform that has it all:
- A 6-inch, 800x600 pixel e-paper display with support for greyscale, partial updates, and accelerated refresh cycles
- An on-board ESP32 microcontroller with integrated Wi-Fi and Bluetooth 4.0 (BLE)
- Extremely low-energy, battery- or USB-powered operation (including a 25 µA sleep state) that wrings days, weeks, or months out of a single charge
- A MicroSD card reader from which Inkplate 6 can pull images to display
- Three capacitive touch pads
- A form factor that's optimized for the design of custom enclosures
- Additional GPIO pins, easyC/Qwiic compatibility, and support for I²C and SPI
- Arduino libraries (100% compatible with Adafruit GFX) and a MicroPython module that facilitate the rendering of text, images, and line art
Limited Only by Your Imagination
Here is a random sampling of things you might want to see hanging from your wall, sitting on your desk, stuck to your refrigerator, tucked away in your bag, or surrounded by a custom frame:
- 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 tally up your likes on social media (if you must). Download updates, and only hit the battery when you do.
- Collaborative Task Tracker - Maintain shared lists of groceries to buy, chores to do, and birthdays to remember. Or replace the power-hungry wall monitor in your office with an e-paper kanban on each desk. Give away your dry-erase markers.
- Minimalist E-Paper Typewriter - Get those words out. Sync them to the cloud or store them on an SD card. And keep distractions like social media and email away from your line-of-sight.
- 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 cameraroll, sure, but why not generate abstract art from sensor data? Or torment your house guests with a modern take on the classic, four shot, black-and-white photobooth?
Whatever your e-paper idea might be, as long as it’s compatible with a six inch screen, Inkplate 6 probably represents your quickest path to it. And even if you’re working toward something larger or smaller, Inkplate 6 can still save you some headaches while you’re prototyping.
Kindles Have Nice Screens
We’d rather see them in your hands than in a landfill somewhere. And by recycling used Kindle screens, e-radionica are able to offer high-end features at an affordable price.
- 3-Bit Greyscale, which allows Inkplate 6 to display black, white, and six different shades of grey (1-bit black & white mode also available)
- 264 ms Refresh, which is unusually fast for an e-paper screen of this size
- Partial Updates, so you don't have to reset the entire screen to add content
Fast Partial Updates
ESP32 is the Place to Be
Inkplate 6 is built around one of today’s most popular microcontrollers. If you already have experience working with ESP32, then you’re in good company. Developing for Inkplate 6 should feel mighty familiar. And if you’re new to ESP32, this is a great way to start learning a set of skills that will serve you well for a long time to come.
The ESP32 WROVER module at the heart of Inkplate 6 features:
- A dual-core microprocessor
- 8 MB of RAM
- 4 MB of flash
- Integrated Wi-Fi & Bluetooth 4.0 (BLE)
Help Us Build an Open E-Paper Community
Inkplate 6 is open hardware, and the software that powers it is open source. You can find both the design files and source code on GitHub. That includes:
- The Inkplate 6 hardware design files, including schematics, Gerbers and the Bill-of-Materials
- The Inkplate 6 Arduino library
- A technical drawing
- A diagram that shows the locations of connectors and plugs
e-radionica have already done a great deal of work to make Inkplate 6 easy to use, but a larger community could accomplish even more. Inkplate’s Arduino and MicroPython ecosystems will only get healthier over time, and they invite you to contribute to the libraries, tools, and frameworks that will help Inkplate 6 (and subsequent models!) mature into the hundreds of different consumer products they want to be when they grow up.
