The reTerminal E1003 is a 10.3 inch touch-supported, open-source monochrome ePaper display featuring 16 levels of grayscale and a high-resolution of 1404×1872 pixels, with up to 6-month battery life. Powered by ESP32-S3, it natively supports our SenseCraft HMI no-code UI platform for effortless dashboard creation. Whether for smart home dashboard visualization and control, office information displays, or educational projects, this ready-to-use touch-enabled device delivers stunning visuals and flexible customization to meet all your needs. Feature Note: Smaller display options are also available within the reTerminal ePaper series, including 7.5'' monochrome and 7.3'' full-color versions. 3-Second Full Refresh for Faster ePaper Responsive Dashboards With an integrated T-CON timing controller, the reTerminal E1003 enables full-display refresh in just 3 seconds, significantly improving responsiveness compared to typical ePaper update performance. It’s ideal for smart home dashboards, control panels, and dynamic status displays that require faster visual feedback with minimal delay. Build Interactive Interfaces Easily with SenseCraft HMI and Touch Support The reTerminal E1003 supports direct design and development with SenseCraft HMI, our no-code UI design platform with ready-to-use UI templates for rapid dashboard creation. With built-in touch support in the SenseCraft HMI firmware, users can wake the display with a simple tap and navigate between pages naturally through finger interaction. Instead of acting as a passive ePaper display, the reTerminal E1003 becomes an interactive control center for smart home panels, status dashboards, and custom IoT interfaces. Crisp Visuals with 16-Level Grayscale and High-Resolution ePaper Display The 10.3-inch ePaper display with 1404 × 1872 resolution and 16-level grayscale support delivers richer visual detail compared to typical monochrome ePaper panels. Whether showing dashboards, UI layouts, or data visualizations, the reTerminal E1003 provides clearer structure, improved readability, and more flexibility for information-rich interfaces. 6-Month Battery Life for Truly Cable-Free Placement Equipped with a built-in 3000mAh battery, the reTerminal E1003 runs up to 6 months on a single charge in the low power mode under a once-per-day refresh scenario. With no wiring required, it can be easily deployed on walls, desks, or anywhere dashboards and control panels are needed. Flexible Hardware & Software Customization Leveraging Seeed Studio’s extensive OEM/ODM expertise, the reTerminal E1003 can be customized to fit your exact needs. Whether you require specific sensors, modified I/O configurations, or tailored UI designs, it’s built to adapt—ideal for industrial, educational, or personal use.
