This is the effect of my brainstorming about the best board to use for Tote's brains. I initially choose the D1 Mini board, and designed a couple of PCBs to use it. However, I did that late at night, and in the morning I didn't remember that I ordered one of the designs. Then I changed my mind and decided to use the Adafruit Feather boards instead. A few weeks later I received the surprise PCBs. Since I already have them, I might as well just built and program it -- especially since the code is going to be the same for both versions of Tote anyways, and I'm still waiting for the other PCBs.
