Some of the components used are very fine pitch BGA so this is not a project for the faint of heart.

This revision 1 prototype has quite a few mistakes that I made in the schematic and layout, but most have been fixed in one way or another. The project (more of an experiment) is well under way and I’m already working on a revision 2 pcb to fix my mistakes and change some things around. Over that past few months I’ve been working on the first revision of my “qwertypi” handheld computer based on a Raspberry Pi Zero W. In late 2015, the Raspberry Pi Foundation released the tiny Pi Zero and subsequent Pi Zero W which sparked my interest in building a handheld again. Back then I didn’t really have the knowledge or skills to follow through with such a project and so it was pushed into the “some day” list.

When the first Raspberry Pi 1 Model B was released in 2012, I was fully immersed in the Zipit Z2 community and I had the idea to create my own handheld qwerty Linux computer with the Pi.
