Adafruit (PID 3200) Teensy 3.x Feather Adapter

The Teensy is my favorite microcontroller  and I use them in almost every project. So what is a Teensy? Is it a  super small Arduino? Well... [Simultaneously] Yes it is. No it's not. If you've watched Voidstar Lab before,  you know I use them in a LOT of projects. [Audio snippets] Teensy! Another Teensy...  A Teensy... Teensy? The Teensy. That Teensy! This video isn't sponsored by Teensy  or anyone. I just... really like Teensies.   [faint crying in background]  And it's not only because I salvaged 20 of them  when my past client threw out an entire run of   prototypes that I painstakingly hand-built and I  ripped them out in between bouts of sobbing. [Dramatic, resounding thuds] They're just great parts.  They have fast processors,   tons of interfaces, a fair price, a  diminutive size, and are compatible   with Arduino and most of its libraries.  So is a Teensy an Arduino? Well... ki
