1.54 inch B/W/R/Y ESL

Ultra-Compact Design: Small footprint ideal for cosmetics, jewelry, electronics, or other small product shelves.

Ultra-Low Power Consumption: Consumes power only during screen updates, enabling years of operation on a single coin cell battery.

High Visibility & Wide Viewing Angle: Reflective E Ink technology provides paper-like clarity and sunlight readability with >170° viewing angle.

Wireless Update Capability: Supports RF (2.4GHz), BLE, or NFC for real-time updates through ESL systems and gateways.
