reTerminal E1002 Full-Color ePaper Display

The reTerminal E1002 is a 7.3-inch full-color e-paper display designed specifically for energy-efficient, long-term applications. It combines the advantages of E-Ink Spectra 6 technology—crisp display in multiple colors—with extremely low power consumption, allowing the device to operate for up to three months on a single battery charge. Powered by a powerful ESP32-S3 microcontroller, the display offers integrated Wi-Fi and Bluetooth for wireless connectivity and easy integration into smart home environments. Thanks to support from the SenseCraft HMI platform, users can design custom user interfaces without programming effort and transfer them directly to the device. At the same time, the reTerminal E1002 is compatible with popular ecosystems such as Home Assistant (via ESPHome), the TRMNL E-Ink Dashboard, as well as Arduino and ESP-IDF, providing maximum flexibility for both beginners and developers. With a resolution of 800×480 pixels, texts, graphics, and photos are displayed clearly and with high contrast. The robust, compact housing of the device houses not only the display but also useful extras such as sensors for temperature and humidity and a buzzer for acoustic signals. Overall, the reTerminal E1002 is ideal as a versatile, always-on display for smart home dashboards, information screens, or creative IoT projects, where elegance, adaptability, and long-lasting battery operation are paramount.
