Overview

Inkplate 4TEMPERA is a compact, all-in-one 3.8-inch touchscreen e-paper device designed for low-power, always-on display applications. Built around the powerful ESP32 microcontroller, it features Wi-Fi and Bluetooth connectivity, a built-in Li-Ion battery, frontlighting, and a wide array of sensors, all enclosed in a sleek 3D-printed case. It’s perfect for makers, developers, and anyone seeking a sustainable e-paper solution, as each device reuses an ED038TH2 E Ink panel that was originally destined for e-waste.
