TRMNL

Dedicated e-ink screen for the content you care about.

Clarity, at a glance

TRMNL is an e-ink display that connects with popular products and renders their most useful information. We believe this black & white, focused, hands-off approach is the best way to stay informed without getting distracted.

Our proprietary device is available for purchase at https://usetrmnl.com, however we also provide guides to build your own device, install and mod our open source firmware, and even point your own device (or ours) at your own web server for end-to-end privacy.

See the other repositories in this GitHub organization and our API docs (https://docs.usetrmnl.com) to get started.
