reTerminal Sticky e-paper note device launches at $50

Seeed Studio has introduced the reTerminal Sticky, a compact e‑paper device that combines a 3.97‑inch, 800 × 480‑pixel E Ink touchscreen with an ESP32‑S3 microcontroller and built‑in magnets. Priced at $49.99 for pre‑order, the unit can be attached to refrigerators or walls to display notes, weather, clocks, or other information, and it supports AI‑driven voice input in English and Chinese.

The Sticky runs on a 750 mAh battery, offers Bluetooth 5.0, Wi‑Fi, a temperature and humidity sensor, and can be controlled via a mobile app, desktop client, or open‑source tools such as Home Assistant. Users may flash third‑party firmware, including CrossPoint Reader, to expand functionality. Shipping is slated for mid‑September, with deliveries to the United States, the United Kingdom, China and the broader EU market.
