Description
Official website : orangepi.org/Orange Pi Zero2/ (Backup)
The OrangePi Zero 2 board is an Open-source Single Board Computer (SBC) of 53x60mm 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 u-boot, kernel, and Devuan root filesystem I built.
Connection and startup
USB-UART serial console connection
On the J3 connector (3 pins male 2.54mm, right behind the USB port, pin 1 on the 2x26pins connector side) :
- pin 1 - GND
- pin 2 - UART RX
- pin 3 : UART TX
SD card boot
The OrangePi Zero 2 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 2 board has two extension ports using common 2.54mm (0.1inch) pitch:
- con4 : 2x13
- con5 : 1x13
