Introducing Adafruit EYE SPI, a new standard for SPI device connection and a feature on many of Adafruit’s latest display breakout boards. This system is based on an 18-pin standard FPC connector / cable pairing and is designed as a STEMMA QT equivalent for displays and other SPI devices. EYE SPI enables quick and easy connection and extension of display wiring, without the mess; just a simple flat cable.
