Pimoroni Presto is 4-inch Desktop Touch Display Development Board with RP2350 MCU and WiFi, RGB LEDs, Qwiic Expansion and More

The Pimoroni Presto is a compact 4-inch wireless desktop touch display development board built around the Raspberry Pi RP2350 MCU, which uses the Raspberry Pi RM2 wireless module, for both WiFi 4 and Bluetooth connectivity.

Designed for desktop use, it features a square 480×480 capacitive touchscreen, 8MB PSRAM, 16MB QSPI flash, a microSD card slot, USB-C power/programming port, and Qwiic/STEMMA QT expansion. It also includes seven RGB LEDs for ambient lighting, a piezo speaker, and comes mounted on a sleek black anodized aluminum stand. Pre-installed with MicroPython, it has various demo apps like a clock, photo frame, and environmental dashboards (requiring Qwiic sensors). With this feature, it targets developers, educators, and hobbyists looking for a visually appealing, WiFi-enabled HMI or IoT interface.

Previously, we have written about various display development boards, including the ESP32-C6-based board, the Lilygo T-Display K230 development board, the LILYGO T-Display S3 AMOLED Plus, and many other Feel free to check those out if you are interested in those.
