Overview
The JicTech JS0266NQ04-A0 is a high‑performance 2.66‑inch active matrix electrophoretic display (EPD), commonly known as E‑Paper. Designed for ultra‑low power applications such as Electronic Shelf Labels (ESL), this module offers a paper‑like reading experience with excellent sunlight readability, wide viewing angles, and bi‑stable image retention – consuming power only during screen updates. With 152×296 pixel resolution, pure reflective mode, and a simple SPI interface, it is ideal for battery‑powered devices, smart retail tags, medical displays, and industrial indicators where low power and high contrast are critical.
