TRMNL gives you a standalone, low-distraction dashboard for the information you want to see at a glance. Its 7.5″ monochrome E-Ink display is suited to ambient updates such as calendars, status panels, reminders, and other slow-changing information without the glare of a traditional screen.
The unit is housed in a soft-touch ABS enclosure with a polished chrome kickstand, so it can sit neatly on a desk, shelf, or bench. The display is always readable in ambient light and is especially useful where you want information visible without another bright LCD or OLED panel.
It is built around long battery life and privacy, with an 1800 mAh battery, USB-C charging, and a secure one-way data polling architecture with no inbound network access. TRMNL also uses an open plugin ecosystem, allowing custom dashboards and integrations across a large plugin library.
Features:
- Incredibly Low Power: E-Ink displays only consume power when the image is actively changing. Once an image is set, it requires zero energy to hold it there.
- Easy on the Eyes: E-Ink screens are not backlit. They reflect ambient light, just like real paper, which significantly reduces eye strain and fatigue.
- Perfect in Bright Light: E-Ink displays excel in bright conditions, becoming even clearer and more contrasted as the environment gets brighter.
- Always On, Without the Drain: The persistent nature of the display means your dashboard can be "on" 24/7 without constantly draining the battery.
- Display: 7.5″ monochrome e-ink display with 4 levels of gray and fast refresh
- Enclosure: Soft-touch ABS enclosure with chrome-plated steel kickstand
- Battery: 1800 mAh battery, upgradeable to 2500 mAh (2–6 month typical battery life)
- Charging: USB-C charging, includes charging cable
- Privacy-first design: one-way data polling (no inbound network access)
- Open plugin architecture: for customization and expansion
- Plugin support: Supports up to 400+ plugins and multiple layout options

Jargon buster
Plain-language definitions for the technical terms used above.
- LCD
- LCD stands for liquid crystal display, a screen technology that uses a backlight and liquid crystals to show images or text. It matters because LCD modules usually need a display driver and enough controller pins or a bus interface to send image data.
- Matter
- A smart home connectivity standard designed to let devices work across different ecosystems. It matters if you want a project to integrate more easily with platforms such as Apple Home, Google Home, or other Matter-compatible systems.
- OLED
- OLED stands for organic light-emitting diode, a display type where each pixel produces its own light. It matters because OLED screens are thin, high-contrast and easy to read for small status displays, but they can be more sensitive to image burn-in than some other display types.
- USB-C
- A modern reversible USB connector used for power and data connections. On this product it matters because it can connect directly to a computer as well as to a microcontroller project.
