Allwinner H3 compact SBC supports 10/100 ethernet

Jun 10, 2023 — by Giorgio Mendoza 904 views

 The WuKong Board H3 Zero is a small single board computer powered by a quad-core Allwinner H3 processor. The board comes with 10/100Mbps Ethernet support and various GPIOs for interfacing external devices.

This board appears to be a Orange Pi Zero LTS clone since it features the same processor and provides very similar peripherals. The product page mentions that the standard version comes with 256MB SDRAM, but it can support up to 512MB. 


  • Allwinner H3 — Quad-Core Cortex-A7 ARM CPU; Mali400 MP2 GPU (up to 600MHz), supports OpenGL ES 2.0

The User Manual indicates that the 26-pin header interface is similar to the pinout of the Raspberry Pi Model A/B. The WuKong board is also compatible with operating systems such as Android, Ubuntu, Debian, etc.

    Also roughly similar to the NanoPi Neo, Zero Pi, etc. This is a common design that works well, however the XR819 WiFi chip used in this board and the “Oranges” is known for being quite unreliable, to the point many users were forced to disable it and plug an external WiFi dongle. Better check at the Armbian forums what is the current status of the FOSS drivers for that chip before buying.

    A cli command to ignore wlan0 and disconnect it is
    $ nmcli device disconnect wlan0
