Description

The 3.7" Waveshare e-paper display uses E-Ink technology that enables image display without backlighting, providing a paper-like viewing experience. The display supports four colors: red, yellow, black and white and offers a wide viewing angle exceeding 170°. The displayed image remains visible even after power is removed, while energy consumption occurs mainly during screen refresh.

This version of the module includes a driver board compliant with the Raspberry Pi HAT+ standard. The board features a 40-pin GPIO connector allowing direct connection to Raspberry Pi and compatibility with platforms such as Jetson Nano, Arduino, STM32 and ESP32. Communication with the display is performed via the SPI interface, while the onboard logic level translator enables operation with both 3.3 V and 5 V microcontrollers.

E-paper technology uses microcapsules containing electrically charged pigment particles suspended in fluid. When an electric field is applied, the particles move within the microcapsules, changing the visible color on the display surface. This solution provides extremely low power consumption and excellent readability in ambient light, making the display suitable for applications such as electronic price tags, warehouse labels, information boards and IoT devices.
