reTerminal E1002: 7.3‑Inch Full‑Color E‑Ink Display — Your No‑Code Smart Home Dashboard & AI E‑Ink Photo Album
What Is the reTerminal E1002?
If you are looking for a power-efficient, always-on display for your smart home dashboard, digital photo frame, retail signage, or meeting room board, you may have come across the reTerminal E1002. So, what exactly is the Seeed Studio reTerminal E1002?
In simple terms, the reTerminal E1002 is a 7.3-inch open-source full-color ePaper display terminal powered by the Espressif ESP32-S3 wireless microcontroller. It is purpose-built for low-power, always-on information display applications, offering up to 3 months of battery life on a single charge.
The device features a stunning E Ink® Spectra™ 6 full-color ePaper display with 800×480 resolution. Unlike traditional LCD or OLED screens that consume power continuously, ePaper technology only draws current when redrawing content — making it ideal for applications where the display stays on for extended periods without frequent updates.
What makes the reTerminal E1002 truly special is its ecosystem. It natively supports SenseCraft HMI — Seeed Studio’s AI-powered no-code UI platform that allows anyone to create professional dashboards through drag-and-drop operations without writing a single line of code. At the same time, it is a fully open-source development platform that supports Home Assistant, ESPHome, TRMNL, Arduino, and ESP-IDF for advanced customization.
This is why you can find the reTerminal E1002 in smart homes as a central information hub, in offices as meeting room displays, in retail stores as digital signage, in classrooms as interactive boards, and in countless other always-on display applications.
Why Choose the reTerminal E1002?
1. Stunning 7.3-Inch Full-Color ePaper Display
The reTerminal E1002 features a 7.3-inch E Ink® Spectra™ 6 full-color ePaper display with 800×480 resolution. The Spectra™ 6 technology delivers vibrant, print-like colors that remain clearly visible even in bright sunlight. With a >170° viewing angle, the display looks great from any position.
Unlike backlit screens that emit blue light and cause eye strain, ePaper displays reflect ambient light just like real paper — making them comfortable for prolonged viewing.
2. Exceptional 3-Month Battery Life
Powered by a 2000mAh rechargeable battery, the reTerminal E1002 can operate for up to 3 months on a single charge. This extraordinary battery life is achieved through the ultra-low power consumption of ePaper technology — the device only consumes power when the screen content is refreshed.
This makes the E1002 perfect for battery-powered, always-on applications like desktop calendars, information dashboards, digital photo frames, and retail signage — applications where frequent recharging would be impractical.
3. SenseCraft HMI — No-Code Dashboard Creation
One of the most powerful features of the reTerminal E1002 is its native support for SenseCraft HMI, Seeed Studio’s AI-powered no-code UI platform.
With SenseCraft HMI, you can:
Create professional dashboards through drag-and-drop operations
Design and deploy custom UIs without writing any code
Visualize data from sensors and connected devices
Deploy dashboards to your reTerminal E1002 in as little as 1 minute
This dramatically lowers the barrier to entry — anyone can build a polished HMI dashboard regardless of their programming experience.
4. Powerful ESP32-S3 Hardware
At the heart of the reTerminal E1002 is the Espressif ESP32-S3 dual-core microcontroller with 8MB PSRAM. This provides:
32MB of SPI Flash for firmware and data storage
2.4GHz 802.11 b/g/n Wi-Fi 4 for wireless connectivity
Bluetooth 5.0 LE for low-energy device communication
Powerful image processing and UI rendering capabilities
5. Rich Onboard Sensors and Peripherals
The reTerminal E1002 comes fully equipped with onboard resources that save users the trouble of external wiring:
6. Sleek Metal Enclosure
The reTerminal E1002 is housed in a sleek, durable metal enclosure that enhances both durability and aesthetics. The device measures 176 × 120 × 17mm without the stand, or 176 × 120 × 53mm with the stand.
7. Open-Source and Highly Customizable
The reTerminal E1002 is not just a finished product — it is also a fully open development platform. It supports:
Arduino IDE and PlatformIO for C++ development
ESP-IDF for professional ESP32 development
ESPHome for seamless Home Assistant integration
TRMNL E-ink dashboard platform
Rust Embassy for Rust-based development
This makes the reTerminal E1002 equally suitable for end-users who want a ready-to-use device and developers who want to build custom applications.
