Description

Official website : http://www.orangepi.org/orangepizero/ (Backup)

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, and a guide to create a minimal system using either Busybox or Devuan.
  • The "SD card creation" section from the "from scratch" page : also provides information to use u-boot, kernel, and Devuan root filesystem I built.

Connection and startup

USB-UART serial console connection

UART debug port

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:

  • con4 : 2x13
  • con5 : 1x13
