Seeed Studio XIAO ePaper Display Board EE04 by XIAO ESP32-S3 Plus is a compact low-power ePaper driver board designed for flexible ePaper projects across the XIAO ecosystem. Based on official Seeed materials, the EE04 is powered by XIAO ESP32-S3 Plus and supports both 24-pin and 50-pin ePaper displays, making it a practical platform for digital signage, electronic shelf labels, smart dashboards, and portable information boards. What makes this product worth focusing on is its broad development path: you can use it with SenseCraft HMI for no-code dashboard building, with ESPHome and Home Assistant for smart home display projects, or with PlatformIO and EEZ Studio for more customized development. The official Seeed documentation also highlights battery support, onboard charging, a hardware power switch, and user buttons that make the EE04 especially suitable for portable and energy-efficient ePaper systems.

Official Seeed documentation covers a general getting started guide, a SenseCraft HMI workflow for browser-based dashboard creation, and an ESPHome guide for integration with Home Assistant. That makes the board a good choice whether you want a code-free HMI path or a more technical YAML and firmware-driven setup. Another important point is display flexibility. Official Seeed material shows that the EE04 can work with multiple supported ePaper sizes through the 24-pin and 50-pin interfaces, but the jumper setting must match the display type. This is a practical product for makers and integrators who want one compact board for different ePaper builds instead of a driver locked to a single panel.
