M5Stack ESP32 Core Ink Development Kit w/ 1.54-Inch e-Paper Display

Description

The M5Stack Core Ink Development Kit integrates an ESP32-PICO-D4 microcontroller with a 1.54-inch e-paper display, creating a platform optimized for battery-powered, always-on IoT applications. The e-ink screen provides a sharp, wide-viewing-angle interface that retains imagery without power, drastically reducing energy consumption compared to traditional LCDs.

Built around a 390mAh LiPo battery and a BM8563 real-time clock, the device supports precise timing and deep sleep modes, enabling deployments lasting weeks or months on a single charge. The onboard expansion ports, including HY2.0-4P and M-BUS connectors, allow for seamless integration of environmental sensors, actuators, or custom add-on boards, extending its functionality for smart agriculture, industrial control panels, or electronic shelf labels.
