## Description

The Adafruit eInk Breakout Friend is a driver board for eInk/e-paper displays with a standard 24-pin FPC connector. It includes all the power supply circuitry and level shifting needed to connect your favourite display (up to tri-colour 4.2") to any development board via SPI. Unlike basic breakouts, the eInk Breakout Friend includes a 256 Kbit (32 KB) SRAM chip that handles frame buffering for you. This means you can drive displays up to 4.2" (300×400 tri-colour) without consuming your microcontroller's precious RAM. The SRAM shares the SPI bus with the display, requiring only one extra chip-select pin. The included Arduino and CircuitPython libraries manage everything automatically — just use it like any Adafruit_GFX compatible display. Key Features 32 KB SRAM Buffer – Offloads frame buffering from your microcontroller (supports up to 300×400 tri-colour) 24-Pin FPC Connector – Compatible with most standard small-to-medium eInk displays Level Shifting – Works with both 3.3V and 5V logic levels Power Supply Circuitry – All required voltage rails for eInk displays built in Enable Pin – Shut down power to the SRAM and display for ultra-low-power operation Configurable RESE Resistor – Default 0.5 Ω, switchable to 3 Ω via solder jumper SPI Interface – Standard SPI connection with shared bus for display and SRAM Also Available eInk Feather Friend (Feather form factor with MicroSD slot) Ideal For Low-power displays for IoT and battery-powered projects E-paper signage and information displays Projects requiring a daylight-readable, bi-stable display Prototyping with eInk displays on any SPI-capable board Package Contents 1× Adafruit eInk Breakout Friend with 32 KB SRAM (assembled) 1× Header strip Important: eInk display is not included. This board works with most eInk displays that have a 24-pin FPC connector — verify your display's pinout is compatible before purchasing.
