(The second part of a running mini-series about the Raspberry Pi Zero, the first part is here).
The Raspberry Pi Zero is an amazing little tinkering trinket. It is among the smallest, cheapest and most efficient single board computers currently on the market, because of its radical design choices. First, it features almost no additional components besides the system-on-a-chip (SoC) and the RAM, which are stacked on top of each other. And second, its connectors are all chosen to be as flat as possible, making this the flattest offering on the market. Logically, these choices open up some doors while it closes others. Because of my personal interest in low-cost embedded/mobile/robotics projects, I’m mainly interested in the doors that open. What follows is thus a slightly biased analysis of the pros and cons of the Raspberry Pi Zero (version 1.3 available since May 2016).
