Raspberry Pi Zero
The Raspberry Pi Zero holds a Guinness World Record since 2017 for the smallest fully functional personal computer, a testament to its ultra-compact design measuring just 65x30mm and weighing only 9 grams. This feature, combined with its $5 price tag upon 2015 release, made it a landmark in computing history by democratizing access to programmable hardware for education and experimentation, much like the BBC Micro or Commodore 64 did in prior eras. In a university museum context, it exemplifies the shift to pocket-sized SBCs that fueled maker movements and STEM outreach, with massive popularity evidenced by millions sold and its role in the best-selling British computer line.

Notables
- Guinness World Record: Since 2017, holds title for smallest functional PC at 65x30mm and 9 grams.
- Sold out worldwide (20,000 units) in 24 hours on Nov 26, 2015; bundled free with MagPi magazine.
- $5 USD board redefined entry-level computing, cheaper than many peripherals.
- Revived 1980s “build-your-own” ethos like ZX Spectrum, amid Cambridge academics’ push to fight CS enrollment drop.
- Ultra-low-cost ARM SBC; sparked pocket robotics/IoT boom with GPIO focus.
- “The $5 Pi”; ad slogan: “100 billion MIPS per dollar!” – (actually 200 MIPS/$)
- Helped Raspberry Pi become UK’s best-selling computer; museum staple for maker/STEM democratisation.
