Raspberry Pi’s make for handy lil computers, but they’re really wonderful when you can connect all sorts of nifty hardware to them: color TFT or E-Ink displays, and sensors are our go-to favorites. 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 slim HAT plugs in and gives you lots of hardware connection options so that many projects become plug-and-play.
MOSI/MISO/SCK SPI pins are connected to the default SPI port on the Raspberry Pi
SDA/SCL I2C pins are connected to the default I2C port on the Pi
Display CS on Raspberry Pi CE 0
Display DC on Raspberry Pi GPIO #25
Display Reset on Raspberry Pi GPIO #27
Display Busy on Raspberry Pi GPIO #17 (used for E-Inks)
Display Backlight on Raspberry Pi GPIO #18 (there’s a jumper to cut/disable this if you want to use the PWM output for other uses like NeoPixels)
Touch CS on Raspberry Pi CE 1
Touch IRQ on Raspberry Pi GPIO #24
The remaining EYESPI pins are not connected, leaving you with plenty of GPIO for other accessory boards.
We also have a Stemma QT connector for the I2C port, to make connecting all sorts of Qwiic/Stemma QT devices super easy, two tactile switches on GPIO #5 and #6 and a slide switch on GPIO #13 which you can use for any sort of interface project or configuration.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
