An Arduino library for driving SPI e-paper (e-ink) displays from Good Display and Waveshare, built on Adafruit_GFX for graphics and text. It supports paged drawing to limit RAM usage as well as full screen buffer and low-level bitmap drawing.

Use cases

  • drive an e-paper display from an ESP32 or Arduino
  • show text and graphics on a Waveshare e-ink panel
  • render images on a Good Display e-paper module with limited RAM
  • build a low-power e-ink weather or status display
  • update e-paper screens using paged drawing to save memory

When to choose

  • you use an Arduino-compatible microcontroller with a supported SPI e-paper panel
  • you need Adafruit_GFX-compatible drawing on e-ink hardware
  • RAM constraints require paged/picture-loop rendering

When to avoid

  • your display uses I2C or parallel interfaces rather than SPI
  • you target non-Arduino platforms without the Arduino ecosystem
  • you need fast full-color display refresh
