eenk is a custom firmware for Xteink ESP32-powered e-ink reader devices that turns them into dedicated interactive fiction players. Stories are written in inkle's Ink scripting language, compiled via the eenky IDE (a fork of Inky), and run on-device using the inkcpp C++ runtime. The project includes a browser-based web flasher for firmware installation and library management over USB with no drivers or WiFi required.
- Supports three hardware models: X3 (ESP32-C3, 792×528), X4 (ESP32-C3, 800×480, USB-C), and X4 Pro (ESP32-S3, 800×480, touchscreen, backlight)
- Uses Papyrix firmware's text layout and rendering pipeline for custom fonts that can be applied per story or globally
- Images (cover art, thumbnails, inlined) are bundled with stories using the same pattern as Inky's web export

Debashis Das writes that the ZecTrix Note 4 is an ESP32-S3 based smart note featuring a 4.2-inch e-paper display and integrated voice capabilities for managing reminders, weather, and schedules. The device offers both monochrome and four-color variants (Note 4C) and includes built-in hardware such as a microphone, speaker, NFC, and a rechargeable battery.
- Uses Espressif ESP32-S3 SoC with vector extensions for machine learning workloads.
- Features community firmware options like Slate or TransitInk OS to repurpose the device.
- The Note 4C four-color variant is notably cheaper than the monochrome version on the manufacturer's website.

Jean-Luc Aufranc writes that Seeed Studio’s reTerminal Sticky is a 3.97-inch magnetic touch ePaper display powered by an ESP32-S3 microcontroller. This device can serve as an e-reader, live dashboard, or home automation controller via support for open-source firmware like Crosspoint, TRMNL, and ESPHome. It features a capacitive touchscreen and edge computing capabilities through its built-in microphone.

Building an affordable Home Assistant dashboard does not require expensive hardware. This guide explores several low-cost methods to create functional control panels and information displays using existing or cheap equipment.
Ways to build a budget dashboard include:
* Repurposing old tablets, phones, or even Kindles from your junk drawer using kiosk browsers or the Home Assistant companion app.
* Purchasing second-hand hardware like older tablets or digital photo frames through online marketplaces.
* Using small ESP32 touchscreen modules for low-power desktop dashboards.
* Implementing E-Ink displays for minimal, always-on information such as weather and calendars.
* Jailbreaking used smart displays to bypass manufacturer limitations and run custom software.

Weather Station designed for the Lilygo T5 4.7 inch Epaper Development Platform. Allows for user-friendly configuration of weather display settings via a web interface.
LILYGO has announced a raft of new microcontroller development boards targeting different niches: a low-frequency LoRa board, an ultra-widescreen display board, a LoRa-equipped ePaper display board, and a CAN bus board. The boards are powered by the Espressif ESP32-S3 microcontroller.
Git contributions e-ink display on an esp32. Show off your commit streaks with this wireless e-ink display. It uses an ESP32 to fetch and display your latest contributions.
This article details a project to create a small desktop appliance with an E-Ink display that shows a user's GitHub activity graph. It uses an ESP32 and a 3D-printed case, configured via a web interface.
An experiment using e-paper displays to show current weather, integrating hardware like ESP32 and Cloudflare Workers for software layers.
The SQFMI Watchy is a fully open-source, hackable ePaper watch based on the ESP32 with a crisp, glare-free 1.54" 200x200 ePaper display which can be programmed using the Arduino IDE and lots of your favourite Arduino/ESP libraries!
