The panels were tested on hardware, and the examples record refresh times. USB CDC logging uses the RP2040's second core to keep serial output flowing during lengthy panel refreshes. ### Source excerpt Developer Mariusz Jurgielewicz has published a Rust example collection on GitHub for the Adafruit Feather RP2040 ThinkInk. The repository started from the rp2040-project-template and covers the onboard red LED on GPIO 13, the NeoPixel, text and graphics on the e-Ink display, dithered tri-color and four-color images, a BME280 over STEMMA QT, SSD1306 and SH1107 OLEDs, [...] ## TICKEY is a clip-on color e-paper display for photos, badges, and desk art DevFeed: [TICKEY is a clip-on color e-paper display for photos, badges, and desk art]() Original publisher: [Read original article]() Author: JC Torres Published: 2026-09-28T10:07:06Z Content type: article Language: en Sources: [Yanko Design]() Topics: [e-ink](), [Secure Boot](), [AI Chat]() Tags: [accessories](), [accessories-gadgets-technology-e-ink-display-picture](), [e-ink-display](), [e-paper](), [esp32](), [esp32-s3](), [firmware](), [gadgets](), [hardware](), [picture](), [technology]() ### AI overview TICKEY is a clip-on display built around a 3.7-inch color e-paper panel, with an ESP32-S3, wireless connectivity, and an open firmware platform for custom behavior. Its driver supports more than 48 native colors and offers refresh modes of 13 seconds and 3 seconds. The device can show photos, badge details, or rotating art, and the display uses power while changing its image. ### Source excerpt This Color E-Paper Clip Is the Polaroid That Digital Photos Never Had A photo you love rarely leaves the phone it was taken on, fading into a camera roll the moment the screen goes dark.

Its standard firmware fetches an image and sleep duration from a server over Wi-Fi; users can instead flash custom firmware or point the standard firmware at a custom HTTP server. The default service supports tiled layouts and private plugins that obtain data by polling a URL or receiving a webhook, with Liquid templates for rendering. The author used a Go program on Cloud Run to turn the family calendar into data for a fridge display. The main friction was coordinating device sleep and tile refresh schedules, which could leave the wrong day displayed. The author also notes an extra $20 charge for the Developer Edition and considers the device somewhat expensive for a neat but nonessential gadget. ### Source excerpt The TRMNL is an 800x600, 1-bit e-ink display connected to a battery and a microcontroller, all housed in a nice but unremarkable plastic case. Because the microcontroller spends the vast majority of the time sleeping, and because e-ink displays don't require power unless they're updating, the battery can last six or more months. It charges over USB-C. When the microcontroller wakes up, it connects to a Wi-Fi network and communicates with a pre-configured server to fetch an 800x600 image to display, and the duration of the next sleep. You can flash your own firmware on the device, or point the standard firmware at a custom server. The company provides an example server, although you can implement the (HTTP-based) protocol in whatever way you wish. I considered running my own server, but thought I would give the easy path a try first to see if it would suffice. The default service lets you split the display into several tiles, and there are a number of pre-built and community-built things that can display in each. None of them worked well for me, but that's okay because you can create your own private ones. They get data either by polling a given URL, or by having data posted to a webhook. The layout is rendered using the Liquid templating system, which I had not used before, but it's reasonably straightforward. I wrote a Go program hosted on Cloud Run which fetches the family shared calendar and converts events from the next week into a JSON format designed to make it trivial to render in the templating system. With a 3D-printed holder, super glue, and some magnets, it's now happily stuck to the fridge where it displays the current date and the family events for the next week. The most awkward part of the default service is managing the refreshes. The device has a sleep schedule, and so do the tiles, which are only updated periodically. So the combination can easily leave the wrong day showing. It would be helpful if the service told you when the device would next up
