Dubbed by its creator as the first truly usable Raspberry Pi tablet, CutiePi is powered by a custom, OSHWA-certified open source board based on Raspberry Pi Compute Module 3+ Lite with 1GB RAM, which uses the same BCM2837 SoC as the Raspberry Pi 3 Model B+ single-board computer. On top of all these open hardware, CutiePi utilizes a highly optimized mobile user interface built using the Qt open-source application framework, called CutiePi shell, and based on the official Raspberry Pi OS (formerly Raspbian).
