Premium 7.3" & 7.5" ePaper Smart Displays & DIY Kits
Welcome to our multi-option ePaper display lineup. Whether you are looking for a fully assembled, ready-to-use smart home dashboard in a sleek metal enclosure, an elegant 3D-printed desktop assistant, or an open-source DIY kit to build your own custom e-ink solution, this selection has you covered.
All four variants feature an ultra-low-power design equipped with a 2000mAh battery that can run for up to 3 months on a single charge in deep sleep mode (6-hour refresh interval). They seamlessly integrate into popular ecosystems like Home Assistant (via ESPHome), TRMNL no-code dashboards, and Arduino/ESP-IDF environments.
Select the individual version below that best matches your setup.
