Adafruit eInk Feather Friend with 32KB SRAM

Easy e-paper finally comes to your Feather with this Adafruit eInk Feather Friend designed to make it easy to add an eInk display. It supports up to tri-color 4.2" displays with a 24-pin FPC connector (display not included).

The eInk display is highly daylight readable, with 'static' image retention even when power is disconnected, mimicking printed paper quality.

This Feather Friend includes a 256 Kilobit (32 Kilobyte) SRAM chip that allows buffering for up to 4.2" 300x400 tri-color displays. This allows you to set up the display content in SRAM and transfer to the eInk display without the need for frame-buffering in the microcontroller's RAM.

Key features include:

• 256 Kilobit (32KB) SRAM chip for buffering
• Compatible with tri-color 4.2" 300x400 eInk displays
• MicroSD socket for image/text storage
• Compatible with CircuitPython and Arduino libraries for easy use
• Comes assembled and tested; header soldering required for Feather connection
• Revamped PCB with Adafruit Pinguin silkscreen as of October 2022

Note: EInk display and extension cable are not included. Verify your eInk display has a 24-pin FPC connector compatible with this Feather Friend.
