LILYGO T5 2.13 Inch E-Paper

Overview

The LILYGO T5 2.13-inch E-Paper board brings 4-level grayscale e-ink capability to the T5 series. Unlike binary black-and-white e-paper panels, this board's 2.13-inch display can render four distinct gray levels at 212x104 pixel resolution, enabling more nuanced graphics, charts, and anti-aliased fonts on the low-power e-ink medium.

The ESP32-D0WDQ6 V3 provides dual-core processing with WiFi and Bluetooth, and the board includes practical features like four custom buttons, a reset button, a TF card socket, a 3D metal antenna with IPEX external antenna interface, and four M2 mounting holes. Battery management is comprehensive, with charge/discharge protection and a physical power toggle switch.

Firmware Compatibility

The T5 2.13-inch supports MicroPython, Arduino, and ESP-IDF. The GitHub repository at LilyGo-T5-Grayscale contains grayscale e-paper display drivers and example sketches demonstrating all four gray levels.
