Orange Pi Zero 3W
Pocket-Sized Edge AI Powerhouse
The Orange Pi Zero 3W is an ultra-compact single-board computer designed to compete directly with the Raspberry Pi Zero form factor while offering significantly higher performance thresholds. Measuring just 65 mm x 32 mm, this tiny board packs a surprising punch by introducing a big-little architecture to the micro-SBC segment, making it an ideal choice for advanced IoT gateways, edge AI development, and lightweight servers. Beyond its processing capabilities, it stands out by supporting dual independent displays via Mini HDMI and USB-C DisplayPort Alt Mode, alongside modern wireless connectivity and a dedicated PCIe 3.0 expansion slot.
