== Summary ==
The 2.13inch e-Paper HAT is an add-on board for Raspberry Pi featuring a 250x122 pixel E-Ink raw display panel. It connects to the Raspberry Pi's GPIO header via the HAT interface and enables displaying static content without power-hungry refreshes.

== 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
