Pimoroni Presto Beta is An RP2350 Powered 4-Inch Touchscreen Display with RGB Backlighting and Wireless Connectivity for IoT Applications

Pimoroni has recently launched the Presto Beta Edition, a versatile, connected desktop display companion powered by an RP2350 chip. It features a 4-inch square touchscreen with a 480×480 resolution, housed in an elegant black aluminium stand with RGB backlighting. This is designed as a programmable display and can show calendar updates, weather reports, photos, digital art, and more. Major features include a piezo speaker, microSD card slot, USB-C connector, Qw/ST breakout support, and 7-zone RGB backlighting. It supports wireless connectivity via the RM2 wireless module (Wi-Fi and Bluetooth) and offers battery power options with no onboard charging hardware. It is suitable for personal productivity, creative displays, or IoT applications.

The heart of the Pimoroni Presto Beta is the RP2350B microcontroller, featuring a dual-core Arm Cortex-M33 processor clocked at up to 150MHz, 520KB of SRAM, and 16MB of QSPI flash for execute-in-place (XiP) functionality. Its capacitive touchscreen ensures smooth and responsive interaction, while the built-in RM2 wireless module (CYW43439) provides 2.4GHz Wi-Fi and Bluetooth connectivity. The device also has a reset button, a boot button, and a USB Type-C port for both power and programming.

Previously, we have covered the Adafruit Feather RP2350, a development board powered by Raspberry Pi RP2350 chip. Pimoroni has not developed any touchscreen display-based product so far. However, the company developed the Clipper HAT Mini, the Pico Plus 2W, and many more Raspberry Pi-based products.
