With the HyperPixel 4.0 Square, Pimoroni has developed a comparatively high-resolution display, especially for single-board computers like the Raspberry Pi. The model supports capacitive input too has a resolution of 720 x 720 pixels with a pixel density of 254 PPI.

The HyperPixel 4.0 Square is, as its name suggests, a square version of the HyperPixel 4.0. The 4.0-inch IPS display has a resolution of 720 x 720 pixels, which corresponds with a pixel density of 254 PPI. The 72 x 72 mm panel can display 18-bit colour (262,144 colours) and has a 60 Hz refresh rate. The latter should the HyperPixel 4.0 Square to display animations and media content smoothly.

Pimoroni stresses that the Square is compatible with all Raspberry Pi units that have a 40-pin connector. The display connects to an SBC via DPI compared to the SPI connector that manufacturers usually use for smaller displays. The Square also incorporates a capacitive touch-screen, although the Adafruit product listing notes that Pimoroni sells a non-capacitive touch panel, too. This costs about US$10 less than the Square does, for reference.

According to the manufacturer, the Square can be installed without any soldering, as it simply plugs into a Raspberry Pi. There is also a special GPIO header for connecting the square to larger Raspberry Pi models. The HyperPixel 4.0 Square costs US$79, but is out of stock at the time of writing. Adafruit will inform prospective buyers of when another batch has been produced, though.
