At just 50 × 55 mm — smaller than a standard business card — the upcoming Orange Pi Zero 4 packs an impressive set of features into an ultra-compact form factor. This new addition to the Orange Pi Zero series delivers an octa-core processor, a dedicated AI accelerator, Wi-Fi 6, Gigabit Ethernet, and 4K video output, all on a board designed for tight spaces.
Same Power, Different Shape
The Zero 4 shares the Allwinner A733 system-on-chip with the Orange Pi Zero 3W, which launched earlier this year. Core performance is identical. The key difference lies in the physical design: the Zero 3W uses a 65 × 32 mm elongated layout, while the Zero 4 adopts a more square 50 × 55 mm footprint. The two boards offer roughly the same surface area but suit different installation needs — the slim form factor for narrow slots, the square one for compact planar layouts.
In short, the Zero 4 is not an upgrade over the Zero 3W. It is simply another form-factor option at the same performance level.
