Technical overview

  • Display resolution: 250 x 122 pixels
  • Interface: HAT (GPIO) for Raspberry Pi
  • Suitable for static displays such as price tags, info boards or status indicators
  • Compatible with Raspberry Pi models with standard GPIO header
  • Supported development environments: C and Python on Raspberry Pi; additional demos for Arduino UNO R3, Jetson Nano, RDK X3, STM32 (CubeMX), ESP32/8266
  • Connection via SPI or parallel interface depending on controller board
  • No active backlight needed – the panel uses ambient light
  • Keep refresh cycles minimal to preserve the E-Ink panel's lifespan

Notes and version constraints

  • Exact pinout and required power supply must be confirmed from the datasheet or hardware documentation
  • When using with other boards (Arduino, Jetson, STM32, ESP32), drivers and initialization sequences are vendor-specific
  • Maximum refresh rate and recommended panel lifespan are not stated in the provided text – please check the datasheet
  • For commercial integration: mechanical mounting, EMC compliance, and operating temperature range must be validated separately
