Introducing the LILYGO T-Wrist E-PAPER ESP32 Development Board with 1.54 Inch Screen! This development board, developed specifically for hobbyists, is loaded with the latest technology and ready to unleash your creativity! With its excellent MCU, powered by the powerful ESP32 processor, you can create anything from small but powerful IoT projects to a wide range of applications that take advantage of its amazing capabilities.

Electronic paper or e-paper is a display technology that mimics the appearance of ordinary ink on paper to produce a low-power, paper-like display. The display can hold static text and images for months without electricity. That is, it can retain text and images even when the power is off.

This E-paper display works with an ESP 32 chip which means that it has wifi and Bluetooth built-in, and can be programmed using the Arduino IDE. You can connect this E-paper display to any Wireless device using either its wifi capabilities or simply connect it to a mobile device using its Bluetooth capabilities.

How E-Paper works

E-paper technology, (or electronic paper), is an innovative type of refreshable display that looks similar to printed paper. It works by using alternating electric fields to manipulate charged particles, creating clear images on the screen without needing constant power.
