TRMNL 7.5" (OG) DIY e-Ink Kit

You're not the type to buy a pre-assembled, sealed-box gadget. You're the type who sees "some assembly required" as a challenge, not a warning. Excellent. The TRMNL 7.5" (OG) DIY Kit is your next weekend project. We give you the brains (a powerful XIAO ESP32-S3 Plus), the beauty (a crisp 7.5" e-ink display), and the battery. You bring the soldering iron, the righteous fury of a failed compile, and a 3D printer.

Why You Want It

Because you're in control. Want a no-code experience to build a slick Home Assistant dashboard in minutes? Pair this kit with a TRMNL BYOD license and unlock a universe of drag-and-drop plugins. Prefer to get your hands dirty with Arduino IDE and craft something truly unique? The open-source hardware won't stop you. This isn't just a product; it's a platform for your next great idea, whether that's a smart calendar, a crypto tracker, or a display that just shows pictures of cats. We don't judge.

Product Notes (AKA The Important Bit)

• License To Build: To access the magical no-code world of TRMNL with its 375+ plugins, you'll need to purchase a TRMNL BYOD license separately. Consider it the key to the city.

Still Here? You Must Be a Builder.

You've scrolled past the warnings and the parts list. You're probably already downloading the STL files for the enclosure. You're the reason we sell kits like this. This isn't just about making a Home Assistant e-paper kit; it's about the satisfaction of making it yours. Stop reading the manifest and start clearing your workbench. It's time to build something cool.
