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
