Pi Zero Pocket Terminal with a BlackBerry Keyboard

I have been sketching a handheld terminal build that feels closer to a BlackBerry than a generic mini cyberdeck: pocketable, keyboard-first, and practical to daily-carry.

The current target is a Raspberry Pi Zero 2 W paired with a BlackBerry Q10 keyboard and a small HDMI display. The planning pass answered three key questions: screen size, missing parts, and what a realistic full BOM looks like.

Design targets

• Form factor: one-hand/pocket-friendly, keyboard-first.
• Display sweet spot: 3.7" to 4.0" for a BlackBerry-like feel.
• Resolution target: at least 480x800 (or 720x720 if panel options make sense).

Below 3.5" gets cramped for terminal work unless fonts are tiny. Above 4.3" starts to feel less “phone-like” and drives enclosure size up quickly.
