Orange Pi Zero 3W Review: Is This $25 Tiny SBC the Ultimate Raspberry Pi Zero 2W Killer?

In the world of compact single-board computers, the Raspberry Pi Zero series has long been the go-to choice for makers, IoT enthusiasts, and embedded projects. But a new contender has entered the ring — the Orange Pi Zero 3W. Priced around $25, this palm-sized board brings serious upgrades: a powerful octa-core processor, 3 TOPS NPU for edge AI, dual video outputs, Wi-Fi 6, and up to 16GB of LPDDR5 RAM.

Is it truly a game-changer, or just another budget SBC? I put it to the test.

First Impressions and Design

The Orange Pi Zero 3W measures just 65mm × 32mm and weighs a mere 14g — almost identical in footprint to the Raspberry Pi Zero 2W, with matching mounting holes for easy case compatibility.

Despite its tiny size, the board is packed with modern features:

• Allwinner A733 SoC** (12nm process): 2× Cortex-A76 + 6× Cortex-A55 cores running up to 2.0 GHz
• RISC-V Xuantie E902 real-time coprocessor (~150–200 MHz)
• Imagination BXM-4–64 GPU
• 3 TOPS NPU for on-device AI acceleration
• Up to 16GB LPDDR5 memory (options from 1GB to 12GB currently available)
• Dual video output: Mini HDMI 2.0 + USB-C with DisplayPort 1.4 (up to 4K@60fps)
• Wi-Fi 6 + Bluetooth 5.4
• 2× MIPI CSI camera interfaces + 1× MIPI DSI
• PCIe 3.0 1-lane FPC socket
• 40-pin GPIO header
• USB 3.0 Type-C support

Performance That Punches Above Its Weight

The jump from the Raspberry Pi Zero 2W’s aging quad-core Cortex-A53 (1 GHz) and 512MB RAM to the Orange Pi Zero 3W is massive. With modern big.LITTLE architecture, faster LPDDR5 memory, and a dedicated NPU, this board handles demanding tasks far better — including local AI inference, 4K video playback, and multi-tasking.

Video decoding is particularly impressive:

• 8K@24fps (H.265, VP9, AVS2)
• 4K@30fps (H.265/H.264)

Standout Features

Dual Display Output** This is one of the biggest differentiators. You can drive a Mini HDMI screen and a USB-C DisplayPort monitor simultaneously — something the Pi Zero 2W simply can’t match.

Connectivity Wi-Fi 6 and Bluetooth 5.4 provide modern wireless performance, while the PCIe FPC slot opens doors for fast storage or expansion modules.

Cooling Orange Pi offers an optional active cooler with heatsink for around $4–6 that keeps temperatures in check without blocking GPIO access.

Software Support The board runs Ubuntu, Debian, Android 13, and more. While Raspberry Pi still leads in software polish and community resources, Orange Pi’s ecosystem is maturing quickly, with mainline Linux support in progress.

Comparison: Orange Pi Zero 3W vs Raspberry Pi Zero 2W

The Orange Pi Zero 3W also compares favorably against the Radxa Zero W3, offering a stronger CPU, NPU, more RAM options, dual displays, and better expansion.

Who Is It For?

The Orange Pi Zero 3W is ideal for:

• Edge AI projects and local inference
• Digital signage and multi-display kiosks
• Compact media players and retro gaming
• IoT gateways, smart cameras, and robotics
• Makers who want more power than the Pi Zero form factor traditionally offered

Potential Drawbacks

• No onboard eMMC/UFS storage in the current version (microSD is the main option, with eMMC coming later)
• Software ecosystem is good but not yet as refined as Raspberry Pi’s
• Availability and long-term driver support depend on the community and Orange Pi’s updates

Final Verdict

The Orange Pi Zero 3W is a compelling upgrade for anyone who loves the Pi Zero form factor but has been frustrated by its limited performance and single-display capability. It delivers modern specs — strong CPU, generous RAM options, AI acceleration, Wi-Fi 6, and dual 4K output — at a very competitive price.

If you need raw performance and modern features in a tiny package, the Orange Pi Zero 3W is currently one of the strongest options available. For pure plug-and-play simplicity and vast community support, the Raspberry Pi Zero 2W still has its place — but the gap has never been smaller.
