the boards

* Pervasive Displays [EPD Extension Kit Gen 4 (EXT4)](https://www.pervasivedisplays.com/product/epd-extension-kit-gen-4-EXT4/), 
* Pervasive Displays EXT4-to-Nano adapter;

and the kit

* ![](https://img.shields.io/badge/-NEW-orange) [E-Paper Development Kit for Matter (EPDK-Matter)](https://www.pervasivedisplays.com), which includes a Pervasive Displays [EPD Extension Kit Gen 4 (EXT4)](https://www.pervasivedisplays.com/product/epd-extension-kit-gen-3-EXT3/) and a Pervasive Displays EXT4-to-Nano adapter boards, a Pervasive Displays [2.9″ 384x168 E-ink monochrome high-definition](https://www.pervasivedisplays.com/product/2-9-e-ink-displays/) with embedded fast update and wide temperature display, an [Arduino Nano Matter](https://store.arduino.cc/pages/nano-matter) board based on [Silicon Labs MGM240S](https://www.silabs.com/wireless/zigbee/efr32mg24-series-2-modules).

The library has also been tested successfully against the [Silicon Labs EFR32xG24 Explorer Kit](https://www.silabs.com/development-tools/wireless/efr32xg24-explorer-kit) board.
