I made a tablet that runs Chromium OS (the open source version of Chrome OS, the OS on Chromebooks). I made it using a 10.1" touchscreen display and a Raspberry Pi 4 computer.

I actually started with a Raspberry Pi 3B instead of the new Pi 4, but I decided to buy the Raspberry Pi 4 to help the tablet work faster.
That's all! Bye!
