Breakout Wiring

Though it looks like a lot of connections, wiring up an eInk breakout is pretty straightforward! Below shows using hardware SPI to connect it to an Adafruit Metro M4.

  • Vin connects to the microcontroller board's 5V or 3.3V power supply pin
  • GND connects to ground
  • CLK connects to SPI clock. It's easiest to connect it to pin 3 of the ICSP header.
  • MOSI connects to SPI MOSI. It's easiest to connect it to pin 4 of the ICSP header.
  • MISO connects to SPI MISO. It's easiest to connect it to pin 1 of the ICSP header.
  • ECS connects to our e-Ink Chip Select pin. We'll be using Digital 9
  • D/C connects to our e-Ink data/command select pin. We'll be using Digital 10.
  • SRCS connects to our SRAM Chip Select pin. We'll be using Digital 6
  • RST connects to our e-Ink reset pin. We'll be using Digital 8.
  • BUSY connects to our e-Ink busy pin. We'll be using Digital 7.
  • SDCS connects to our SD Card Chip Select pin. We'll be using Digital 5
