A 128x64 pixel, 2.15" LCD display with snazzy six-zone RGB backlight and six capacitive touch buttons. GFX HAT makes an ideal display and interface for your headless Pi projects.
GFX HAT riffs off our beloved Display-O-Tron HAT, but gives you the flexibility of individual pixels, letting you display more complex graphics and real typefaces, while retaining the handy capacitive touch buttons for input/navigation.
Features
- 128x64 pixel, 2.15" LCD display
- Integrated diffuser/reflector assembly
- Six-zone RGB LED backlight
- SN3218 LED driver chip (I2C address 0x54)
- Six capacitive touch buttons with white LEDs
- Microchip CAP1166 capacitive touch/LED driver chip ((I2C address 0x2c)
- Compatible with Raspberry Pi 3B+, 3, 2, B+, A+, Zero, and Zero W
- Python library
- Comes fully assembled
Software
Our Python library handles displaying on the LCD, controlling the backlight, and linking functions to the touch buttons. We've also included a couple of examples to get you started.
Our software does not support Raspbian Wheezy.
Jargon buster
Plain-language definitions for the technical terms used above.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- I2C address
- An I2C address is the number a device uses so a microcontroller can tell it apart from other devices on the same I2C bus. It matters because two devices with the same fixed address may conflict if used together.
- LCD
- LCD stands for liquid crystal display, a screen technology that uses a backlight and liquid crystals to show images or text. It matters because LCD modules usually need a display driver and enough controller pins or a bus interface to send image data.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- LED driver
- An LED driver is a control chip or circuit that supplies and switches power to LEDs. For a display board, it reduces the number of microcontroller pins needed and handles tasks like lighting the right segments and adjusting brightness.
- RGB
- Short for red, green and blue, usually referring to an LED that can mix those three colours. It matters because controlling an RGB LED teaches how separate outputs combine to create different colours.
