Want a low-power display for your smart home dashboard, calendar, or weather panel? This one quietly nails it.
Let’s be honest—your smart home doesn’t need flashy OLEDs or screens that draw constant power. What it does need is a calm, always-on display that sips energy, looks elegant on the wall, and feels like paper. That’s where the XIAO 7.5” ePaper Panel shines.
This isn’t just a dev board for nerds (though we love that too). It’s the perfect interface for ambient information in your smart home: weather, calendars, timers, reminders, grocery lists—all passively displayed, even when the power cuts out.
And yes, it looks fantastic while doing it.

Why Smart Homes Love E-Paper
The XIAO 7.5” ePaper Panel displays static data with paper-like clarity, perfect for dashboards that shouldn’t scream for attention. Imagine a weather panel near your front door, a family calendar in the kitchen, or a minimal task list in your office.
Once an image is written to the screen, it stays without drawing power. This means no screen burn, no brightness battles with sunlight, and no charging stress.
It refreshes in about 4 seconds, which is fine for non-dynamic content—and honestly, in a smart home, that’s the kind of pace you want: slow, reliable, ambient.
Design & Feel: “Built to Blend In”
It’s crazy thin. Like, you-can-glue-it-to-a-wall thin. At just 1.2 mm, this panel disappears into any interior. The matte surface is non-reflective and clear under sunlight, which makes it ideal for home use near windows or in bright kitchens.
No lights, no fanfare, no clutter—just clean, modern design that whispers “I belong here.”
Home Testing: Calm Control Center
I wired it to a Seeed XIAO MCU and built a home dashboard: calendar, current temp, humidity, and even the washing machine’s status (thanks, MQTT).
It used almost zero battery. I left it running for 3 days on a coin cell. The screen? Crisp, legible, and almost meditative. My favorite moment: someone asked me if it was a printed sign—it just blends that well.
Perfect for entryway info boards, kitchen to-dos, or even “do not disturb” signs on office doors.
