This $48 e-paper display can be whatever you want it to be

E-paper displays now offer a low-cost, customizable information hub for your desk or kitchen, independent of subscription services.

Seeed Studio and TRMNL have partnered to release a $48 DIY e-paper display kit. The kit includes a 7.5-inch monochrome e-paper display with an 800x480 resolution, a control board with an ESP32-S3 microcontroller, a battery, and a Wi-Fi antenna. Users can set up the display using TRMNL's cloud service, which has a $50 one-time license fee after a 14-day trial, or opt for a self-hosted solution using open-source firmware like Terminus. The Seeed Studio hardware is designed to work with TRMNL's firmware, plugins, and hosted service, but also offers compatibility with platforms like Home Assistant for users who prefer to manage their own servers. The project was initiated after a community member inquired about running TRMNL firmware on a Seeed Studio e-paper panel, leading to an official partnership announced in July 2025.

The launch of this $48 e-paper display kit signifies a growing trend towards affordable, customizable hardware for personal information management, catering to DIY enthusiasts and users seeking alternatives to proprietary smart home ecosystems. The dual approach of offering both a managed cloud service with a one-time fee and open-source self-hosting options addresses different user preferences for convenience and control. This strategy positions the product to appeal to a broad segment of the maker and tech community, fostering a platform for custom plugins and applications.

The collaboration between Seeed Studio, a hardware manufacturer, and TRMNL, a firmware and platform company, highlights a successful model for bringing specialized DIY electronics to market. By leveraging Seeed's established hardware expertise and TRMNL's software ecosystem, they've created a product that is both accessible and versatile. The emphasis on an open-source option like Terminus also appeals to privacy-conscious users and developers, potentially leading to a rich community of independently developed plugins and integrations.
