The OrangePi Zero board is an Open-source Single Board Computer (SBC) of 48x46mm created and sold by Xunlong.
Base system
- Create initial system from scratch (sources): all the steps, using u-boot and Linux kernel sources.
- Rootfs guide to create either a minimal system using Busybox or a full Devuan GNU/Linux system.
- The "SD card creation" section from the "from scratch" page also provides information to use the u-boot, kernel image, and Devuan root filesystem I built.

Connection and startup
USB-UART serial console connection
On the J3 connector (3 pins male 2.54mm, next to the Ethernet connector, pin 1 on the board edge) :
- pin 1 - GND : Black
- pin 2 - UART RX : Orange
- pin 3 : UART TX : Yellow
SD card boot
The OrangePi Zero board boots from the SD card which has to be prepared following specific steps. Follow the "SD card creation" section from the "from scratch" page
Extension ports
The OrangePi Zero board has two extension ports using common 2.54mm (0.1inch) pitch:
