EYESPI Cable - 18-pin 200mm FPC A-B Type
200 mm flexible PCB (FPC) cable with 18-pin connectors in A-B orientation (pin 1 matches pin 1 on both ends). Used with Adafruit EYESPI displays and breakouts where more reach is needed.

Display/interface power pin. Adafruit says to connect to the same power as the microcontroller logic level, for example 3V on a Feather or 5V on an Arduino.
Common ground for power and logic.
I2C serial clock line.
I2C serial data line.
SPI clock input.
SPI MOSI line, used to send data from the microcontroller to the SD card and/or display.
SPI MISO line, used for the SD card; Adafruit notes it is not used for the write-only display path.
Display SPI data/command selector.
Display reset line. Connecting to ground resets the display.
TFT or eInk SPI chip select.
General-purpose GPIO line on the EYESPI interface.
General-purpose GPIO line on the EYESPI interface.
Touch screen chip select.
Memory chip select, required for communicating with onboard RAM when present.
SD card chip select, required for communicating with onboard SD card holder when present.
PWM input for backlight control, pulled high by default; can be PWM-controlled or pulled down to turn the backlight off.
Busy-detect line used by eInk displays; optional according to Adafruit.
Capacitive touch interrupt line; goes low when a touch is detected and is only needed for capacitive touch displays.
