Raspberry Pi has introduced a 5-inch version of its Touch Display 2 with the same 720 × 1280 (portrait) resolution as the updated 7-inch model, but at $40. It's available now through Approved Resellers, giving you a smaller plug-and-play touch option.
Aside from the smaller footprint, the specification mirrors the 7-inch unit: a capacitive multi-touch panel with five-finger input, an active area around 62 × 110 millimeters, and full Raspberry Pi OS support. The display draws power from the host board. The box includes the cables, connectors, and mounting hardware you need.
Physically, this is a 24-bit RGB LCD thin-film-transistor panel with an anti-glare finish. You attach your board to the rear standoffs and link the display over the Display Serial Interface with the included flat-flex cable. One note: it doesn't support Raspberry Pi Zero or Pico boards, and because it takes power from the General-Purpose Input/Output header, you'll need a workaround if you also plan to stack a Hardware Attached on Top accessory. Viewing angles are a touch narrower than the 7-inch unit.
The thin bezel is purpose-built for recessed or enclosed installations, not standalone use. This orientation suits embedded deployments like museum labels, retail point-of-sale terminals, and in-wall or chassis-mounted smart-home controls, where a flush fit helps.
There are, however, trade-offs to consider. Because the display pulls five volts from the GPIO header, stacking a HAT may require a workaround, as the header area is typically blocked in common mounting configurations. And with no Zero or Pico support, some ultra-compact or microcontroller projects are off the table.
