Product Description
The Waveshare 2.9″ e-Ink Display Module (SPI Interface) is a compact reflective e-paper display suitable for low-power embedded systems, wearable devices, and battery-operated IoT projects. Its 2.9-inch screen with 296×128 resolution provides clear black and white text and graphics without a backlight. E-ink technology consumes power only during screen refresh, enabling long battery life for static display applications such as dashboards, schedules, readers, sensor status screens, and information boards.
This module communicates over SPI, allowing seamless interfacing with microcontrollers like Arduino, ESP32, Raspberry Pi (with SPI pins), and STM32. Its sunlight-readable panel and minimal power requirements make it ideal for always-on displays in IoT solutions and smart embedded systems.
