Seeed Studio introduced the reTerminal E on September 4, 2025, with two ESP32-S3 ePaper displays: the monochrome E1001 and color E1002. The family has since grown to four models, adding a larger touch-enabled monochrome option and a larger color display. The choice comes down to screen size, color, refresh speed, touch, and how you plan to create and deploy content.
What Seeed launched in 2025
Seeed’s September 4, 2025 announcement introduced the reTerminal E as a ready-to-use ePaper human-machine interface for smart homes, offices, and other shared spaces. The original lineup consisted of the 7.5-inch monochrome E1001 and 7.3-inch full-color E1002, alongside SenseCraft HMI, a no-code platform for designing and deploying display interfaces. Seeed described onboard temperature and humidity sensing, a buzzer, microphone, physical controls, and rechargeable batteries. These are manufacturer descriptions, not results of independent testing.

Seeed estimates battery duration at about three months for E1001 and E1002 and about six months for E1003 and E1004. These are manufacturer estimates; the overview does not establish independent test results or a universal usage pattern behind the durations. Seeed’s current family overview
How to choose between the four models
E1001: monochrome information that changes quickly
The E1001 is the smaller monochrome model in the original launch lineup. Seeed lists partial refresh and a 2–5 second refresh time, making it the family’s option for text-heavy information that benefits from more frequent updates. Seeed recommends it for lower-cost, text-focused use; current pricing is not established by the launch announcement. Seeed’s current family overview
Rank #2

E1002: color on the original-size display
Choose the E1002 if color matters more than fast refresh. Its 7.3-inch, 800 × 480 panel uses E Ink Spectra 6, but Seeed lists a 15–20 second refresh and no partial refresh. That slower update profile is an important trade-off for dashboards or imagery that change often. Seeed’s current family overview
E1003: larger monochrome screen with touch
The E1003 combines a 10.3-inch, high-resolution monochrome panel with 16 grayscale levels, touch, and partial refresh. Seeed lists a 2–3 second refresh. Touch support in Seeedash requires version 1.1.2 or later, according to the family overview. Seeed’s current family overview
Rank #3
- 13.3" FULL-COLOR ePAPER DISPLAY – Showcase photos, artwork, dashboards, and information on a spacious 1200 × 1600 E Ink Spectra 6 full-color ePaper display with a paper-like viewing experience and ultra-low power consumption.
- BUILT FOR DIGITAL FRAMES & COLOR DASHBOARDS – Turn photos, artwork, schedules, and live information into always-on visual displays. The large color ePaper screen is ideal for digital frames, home dashboards, office information displays, and other low-refresh visual applications.
- UP TO 6-MONTH BATTERY LIFE – A built-in 5000mAh rechargeable battery and energy-efficient ePaper display enable flexible placement without continuous power. Battery life can reach up to 6 months in low-power mode with a 6-hour refresh interval; actual runtime varies by usage.
- BUILT FOR MAKERS & OPEN-SOURCE DEVELOPMENT – Powered by ESP32-S3 with 8MB PSRAM and 32MB Flash. Build quickly with SenseCraft Seeedash, integrate with Home Assistant through ESPHome, or develop with Arduino and ESP-IDF for fully customizable projects.
- WIRELESS, SENSORS & EXPANDABLE I/O – Connect through 2.4GHz Wi-Fi and Bluetooth 5.0, monitor temperature and humidity with onboard sensors, and expand storage via microSD up to 32GB with a 16GB card included. UART, I2C, GPIO, and ADC interfaces support additional sensors and peripherals.
E1004: largest screen for color content
The E1004 is the family’s largest listed model, with a 13.3-inch color Spectra 6 display. Seeed lists a refresh time of about 20 seconds. Its size and color suit image- or photo-frame-style display use better than content that needs frequent updates; that is also Seeed’s stated positioning. Seeed’s current family overview
Shared hardware and physical setup
Seeed lists the same core platform across the four models: ESP32-S3, Wi-Fi 4, Bluetooth 5.0, a temperature and humidity sensor, buzzer, USB-C 5 V/1 A input, and metal enclosure. Details vary by model, so check the guide for the specific unit rather than assuming every accessory or component is identical. Seeed’s current family overview
Rank #4
- USHTS: 8524990000 JPHTS: 852499000 TARIC: 8524990000
The E1001 and E1002 guides specify an ESP32-S3 with 8 MB PSRAM and 32 MB flash, microSD support up to 32 GB using FAT32, 2.4 GHz Wi-Fi 802.11 b/g/n, a reserved microphone, and a 2,000 mAh battery. Both guides list a 0–40 °C operating range. The E1001 box contents include a charging/data cable, screws, screwdriver, quick-start guide, and 3D-printed stand; do not assume other models include the same items. E1001 guide E1002 guide
