Pimoroni HyperPixel 4.0" Touch

The Pimoroni HyperPixel 4.0" Touch is a 4″ IPS LCD with a resolution of 480×800 pixels in 18-bit colour and a capacitive touchscreen. It sits on the Pi's 40-pin header and the pixels travel over DPI - no HDMI cable, and a refresh is instant. That makes it a good fit for clocks, dashboards and anything that animates or reacts to a finger.

Pimoroni sells this board with and without touch, and as a square 720×720 sibling - pick the FrameOS device that matches yours: HyperPixel 4.0", HyperPixel 4.0" Square, HyperPixel 4.0" Square Touch. The smaller round one is the HyperPixel 2.1" Round.

Needs FrameOS 2026.9.20 or newer.

How it works

One native driver covers every HyperPixel 4.0 - no Pimoroni installer, no Python. On the first deploy its setup writes what the panel needs into config.txt and the frame reboots once. How the pixels get to the glass depends on the Pi, which the frame detects by itself:

• Pi Zero to Pi 4 - the Pi's firmware drives DPI into /dev/fb0, and FrameOS sends the panel its init sequence and switches the backlight over GPIO.
• Pi 5 - a Pi 5 has no firmware DPI, so setup enables the kernel's vc4-kms-dpi-hyperpixel4 overlay instead and FrameOS only writes the framebuffer.

Touch is read by the kernel's own Goodix GT911 driver and arrives in your scenes as the pointer events mouseMove, mouseDown and mouseUp. Coordinates follow the frame's rotate and flip settings, so a scene on a rotated panel gets taps where it drew things.

Setup

1. Plug the display onto the Pi's GPIO header. On a Pi Zero that means soldering a header first - or buy the pre-pinned WH / 2 WH.
2. Add a frame and select the Pimoroni HyperPixel 4.0" Touch device.
3. Save & deploy. The first deploy reboots the Pi once, then the scene appears.

The panel scans in portrait, 480×800. For an 800×480 landscape frame set Rotate to 90 or 270 in the frame's settings.

The HyperPixel takes every GPIO pin, so the Pi's I2C and SPI buses are switched off while it is the frame's display - no other HATs or GPIO buttons alongside it. Turn display off / on (from the frame's menu, or on a schedule) switches the backlight; there is no dimming.

Moving the SD card to a different HyperPixel is fine: change the device, deploy, and setup swaps the config.txt lines over.

Status

🟢 Confirmed working on a Raspberry Pi 5 - picture, touch and display off / on. The Pi Zero to Pi 4 path shares its design with the confirmed 2.1" Round driver but hasn't been tried on this panel yet. If you run one, tell us on GitHub or Discord.
