3.6inch E-Paper HAT+ Full Color E Ink Display 600×400 SPI, Low Power ePaper Screen Module for Raspberry Pi, Arduino, ESP32, 40PIN HAT Plus Price Tag Shelf Label

Overview The 3.6 inch e-Paper HAT+ (E) is a compact full color E Ink display module that combines a 3.6 E Ink Spectra 6 e-paper panel with a HAT+ standard driver board. With a 600×400 resolution (~200 ppi) and wide viewing angle, this 3.6 inch e-paper display delivers crisp, paper-like images that are easy to read under ambient light. It is ideal for price tags, shelf labels, asset tags, conference name badges and industrial instrument panels where low power and high readability are important. Unlike traditional LCDs, this E Ink e-paper display has no backlight and is passively reflective, so it looks like printed paper in normal room or daylight conditions.

The E-paper panel keeps the last image even when power is removed, and power is basically only required during screen refresh. This makes the 3.6 inch E Ink Spectra 6 display an excellent choice for battery-powered and energy-saving projects where the content does not change frequently. The module uses an SPI interface and includes an onboard voltage translator, so it is compatible with both 3.3 V and 5 V microcontrollers. You can easily connect this SPI ePaper display for Raspberry Pi, for Arduino, STM32, ESP32 and other popular controllers as a simple SPI peripheral.

Official resources provide sample code and driver examples for Rasp-berry Pi / Jetson Nano / Ar-duino / STM32 / ESP32, helping you get started quickly with the E-paper HAT+ in different environments. As a HAT+ standard ePaper HAT, the board features a 40-pin GPIO header compatible with Rasp-berry Pi-style pinouts. The HAT+ standard improves interoperability and makes it easier to stack this e-Paper HAT Plus with other expansion boards in compact systems. The overall design remains low-voltage and display-onlythere are no wireless, RF or high-power circuits, making it a safe choice for classroom, lab and hobby projects focused purely on E Ink display output.

Using E Ink Spectra 6 full color technology, the 3.6 inch full color e-paper display combines
