I was [interested in [connecting the Yun to a motor shield or a Zumo|ArduinoYúnInterfacing], so I contacted Adafruit, Arduino.cc and Pololu, the latter makes the Zumo to get some help.

Despite being a 400MHz processor and being connected directly via an ethernet cable, it is good to remember that the AR9331 on the Yún is still quite a small computer. It's not as fast as a Raspberry Pi (a Pi 3 B+ runs at 1.1GHz) and you can run out of memory (and need to reboot) sometimes.

The {{tcsh}} is just a personal preference, rather than using the native bash shell. With the customised prompt (below) I get a nice colorful prompt. And yes, it's possible to do this with bash, but tcsh has a lot of nice features that I'm accustomed to. The {{blkid}} was used for setting up a swap memory space but is otherwise unnecessary. {{vim-full}} replaces the very-minimal version of the {{vi}} editor already included.

The Yún comes with Python 2 but I want to use Python 3, so I installed Python3 and the python package installer program {{pip3}}. The {{python3}} package installs the entirety of Python 3, so it seems {{python3-light}} is meant to generally suffice for most people. Based on the difference in install times, it's ''significantly'' smaller. Install pip3, upgrading the setuptools, smbus2 (for I²C support), etc.:
