The Adafruit RP2040 Feather ThinkInk makes it easy to connect almost any common e-Paper/e-Ink display with a standard 24-pin FPC connector. E-paper displays retain their image even when power is completely disconnected, and offer high contrast with excellent daylight readability — just like printed paper.

The RP2040's generous 264 KB of internal SRAM provides plenty of buffer space for even the largest supported displays (tested up to 5.6" 7-colour ACeP). The e-paper display gets its own dedicated SPI port, leaving the main Feather SPI free for other peripherals.

Key Features

  • RP2040 Processor – Dual-core Cortex M0+ at 133 MHz with 264 KB RAM and 8 MB QSPI flash
  • 24-Pin FPC Connector – Supports common e-paper displays from 1.54" to 7" diagonal (no soldering required)
  • Dedicated Display SPI – Separate SPI port for the e-paper display, keeping the main SPI free
  • Built-in Power Supply Circuitry – Level shifting and voltage generation for the e-paper display
  • 21 GPIO Pins – Including 4× 12-bit ADC, 2× I2C, 2× SPI, 2× UART, 16× PWM
  • STEMMA QT Connector – Plug-and-play I2C for sensors and peripherals
  • USB Type C – For programming, serial debugging, and power
  • LiPo Battery Support – Built-in 200 mA+ charger with automatic USB/battery switching
  • NeoPixel + Red LED – RGB NeoPixel for status indication plus pin 13 red LED
Important: E-Ink display and extension cable are not included. This board works with e-paper displays that use a 24-pin FPC connector (commonly found on "smart label" style displays from 1.54" to 7"). It is not compatible with larger e-reader displays (such as Kindle screens) which use a different interface. Check the schematics to verify your display is compatible before purchasing.
