Adafruit E-Ink Display Breakout Friend

Adafruit E-Ink Display Breakout Friend provides power supply support circuitry and level shifting to enable E-Ink/E-Paper displays to be attached to development boards. The 24-pin E-Ink Friend features a 32KB SRAM chip that allows users to control the 4.2" tri-color display. The SRAM can set up the display and shuffle the data to E-Ink when needed. The chip also can be interfaced as if it were an Adafruit_GFX compatible display, or its CircuitPython or Arduino libraries will automatically use the microcontroller/microcomputer internal RAM. The board does not come with an E-Ink display.
