Inky wHAT is a 4.2" ePaper/eInk display HAT for the Raspberry Pi, offering 400 × 300 pixels in red, black, and white. The large, high-contrast display is perfect for e-readers, weather dashboards, calendars, and information displays that only need occasional updates.

Comes fully assembled — just pop it onto your Pi's 40-pin header and run the installer. Broken-out I2C and SPI pins on the back let you connect additional sensors and breakouts, displaying their data directly on the ePaper screen. Display refresh takes approximately 25 seconds.
