Compact touch display for Pico projects

This 2.8-inch IPS module adds a 320×240 colour touchscreen to a Raspberry Pi Pico. It connects through the onboard female header using the SPI bus driven by an ST7789 controller. A dedicated XPT2046 resistive touch chip handles input, and a MicroSD slot stores images for direct display. The unit runs from a 5 V supply with programmable backlight control.

Low-power operation with simple wiring

The display draws modest current from the Pico’s 5 V rail and the programmable backlight lets software reduce brightness when full output is not needed. No active cooling is required and the SPI interface keeps pin usage low. Resistive touch sensing works with a stylus or gloved finger without extra drivers.

320×240 resistive SPI panel with MicroSD

The single specification that decides fit is the 320×240 SPI interface paired with the XPT2046 resistive controller. Buyers who need capacitive multi-touch, higher resolution, parallel RGB or HDMI input cannot use this module. It is built for direct Pico attachment and basic GUI or image-viewing tasks.

Questions about this item

How do I connect the 2.8" SPI IPS touch display to a Raspberry Pi Pico using the onboard header?

Align the display's female pin header with the Pico's GPIO pins and press firmly; the SPI bus and touch controller XPT2046 share the connection, so no extra wiring is needed.

What component on the 2.8" display will wear out first with repeated touch use?

The resistive touch layer driven by the XPT2046 controller is the part that degrades over time with heavy pressing.

At what point does the backlight on the 2.8" ST7789 display become the limiting factor during continuous operation?

The programmable backlight running at 5 V will hit its thermal and brightness ceiling before the ST7789 driver or SPI interface does.
