TRMNL X

10.3" E-Ink Dashboard

Overview

TRMNL is a battery-powered e-ink display that connects to your data sources and renders them as glanceable dashboards. Choose from 779+ pre-built integrations or build custom dashboards using any API with HTML/CSS templating.

Typical deployments include sales metrics, calendars, operational status boards, and internal announcements. One-way communication architecture ensures your network remains isolated — the device pulls data from the server, never the reverse.
