Even better is when we make it fast and effortless to wire these up. With this new EYESPI Pi Beret, there's no more counting pins or noodling with a breakout board. This \u003ca href=\"https:\/\/www.raspberrypi.com\/news\/introducing-raspberry-pi-hats\/\"\u003eslim HAT\u003c\/a\u003e plugs in and gives you lots of hardware connection options so that many projects become plug-and-play.\u003c\/p\u003e \u003cp\u003eOur most recent display breakouts have come with a new feature: an \u003ca href=\"\/zh\/search?q=EYESPI+Cable+-+18+Pin\u0026amp;narrow_by=\u0026amp;sort_by=relevency\u0026amp;page=1\"\u003e18-pin \"EYE SPI\" standard FPC connector\u003c\/a\u003e with a flip-top connector. This is intended to be a sort of \"STEMMA QT for displays\" - a way to quickly connect and extend display wiring that uses a lot of SPI pins. In this case, we need a lot of SPI and accessory pins, and we want to be able to use long distances, so we go with an 18-pin 0.5mm pitch FPC.\u003c\/p\u003e \u003cp\u003eWith such a slim and flexible cable, it's easy to have displays anywhere without them physically attached to the Pi like in our \u003ca href=\"\/zh\/search?q=PiTFTs\u0026amp;narrow_by=\u0026amp;sort_by=relevency\u0026amp;page=1\"\u003ePiTFTs\u003c\/a\u003e.
