Part I: introducing the Orange Pi Zero 3W SBC
The Orange Pi Zero 3W has just been released, offering a compact, budget-friendly development board with multiple interfaces, including dual video outputs.
Shenzhen Xunlong, the company behind the popular Orange Pi brand, has just launched a new product: the Orange Pi Zero 3W development board. This compact board features an Allwinner A733 octa-core processor and a Risc-V E902 core coprocessor, also known as the Alibaba XuanTie E902, which operates as a real-time clock at approximately 150 MHz. The Risc-V core utilizes an open instruction set and is designed for low energy consumption.
The processor includes a dual-core Arm Cortex-A76 and a hexa-core Arm Cortex-A55, all built on a 12nm process and utilizing a big-little architecture. The processor features a maximum clock speed of 2.0GHz and supports a 3 Tops NPU, making it ideal for edge AI acceleration applications.
Additionally, while it currently supports up to 12GB of RAM, this board can accommodate up to 16GB of LPDDR5 memory and is capable of decoding video formats up to 8K at 24fps for H.265, VP9, and AVS2. It also supports video formats up to 4K at 30 frames per second for both H.265 and H.264, which is another significant advantage.
Interfaces
This board features a variety of interfaces, including PCIe 3.0, USB Type-C 3.0, UFS, MIPI-CSI, MIPI-DSI, and a 40-pin expansion interface, along with other commonly used functional interfaces. It is compatible with operating systems such as Ubuntu, Debian, and Android 13.

Applications
The Orange Pi Zero 3W offers a robust hardware foundation for the deployment of generative AI and artificial intelligence algorithms in specific scenarios. It can be applied widely in fields such as smart industrial control, intelligent commercial displays, retail payment systems, smart education, commercial robotics, in-vehicle terminals, vision-assisted driving, edge computing, smart distribution terminals, and more.
Storage Options
For those with a keen eye for details, you may have noticed that the W3 board currently lists flash eMMC and UFS storage as future optional upgrades, likely due to global flash chip shortages. Currently, its primary storage option is a TF card slot that supports up to 128GB, which should be more than enough for running Ubuntu or any lightweight Linux distribution.
So, what’s truly new about this board?
If you are curious about what sets this tiny board apart from previous models, it includes Wi-Fi 6 connectivity with Bluetooth 5.4 support, as well as two video output interfaces: one Mini HDMI and one USB-C (DP) DisplayPort 1.4 output, both capable of decoding video up to 4K at 60 fps. Additionally, this board supports a variety of RAM configurations, with options ranging from 1GB to 8GB, and the potential for 12GB and 16GB.
