The E-Ink Gizmo adds an e-ink display to you Circuit Playground, but it also adds some other extras. Let's take a look!

Power Pins

  • VOUT - power input, connect to 3-5VDC.
  • GND - power and signal ground. Connect to your power supply and microcontroller ground.
  • 3.3V is the output from the onboard 3.3V regulator. If you have a need for a clean 3.3V output, you can use this! It can provide at least 100mA output.

SPI Display Pins

  • The display used on the E-Ink Gizmo is a 1.54" tri-color e-Ink display.

    • SCK - this is the SPI clock pin, its an input to the chip. This is connected to A4 or SCL.
    • MOSI - this is the Microcontroller Out Serial In pin, for data sent from your processor to the e-ink display. This is connected to A5 or SDA.
    • CS - this is the chip select pin, drop it low to start an SPI transaction. Its an input to the chip. This is connected to A6 or RX.
    • DC - this is the e-ink SPI data or command selector pin. This is connected to A7 or TX.
    • RST - this is the E-Ink ReSeT pin. It is connected to A3.

E-Ink Display

  • Front and center is a 1.54" 152x152 tri-color e-ink display, with black and red ink pixels and a white-ish background.
  • The display cable goes through to the back and connects to the display connector towards the top in the middle of the back.

Speaker Connector

  • On the bottom of the back, there is a Molex Picoblade speaker connector and a class D amplifier connected to pin A0.
  • The location is labeled on the front as A0 with a speaker symbol.

STEMMA Connectors

  • On the sides of the back are two 3-pin STEMMA connectors for hooking up NeoPixels or servos connected to pins A1 and A2.
  • The locations are labeled on the front as A1 and A2.
