Just got a $3 WeMos D1 Mini in the mail and I thought I would share a few very quick thoughts about it.
- This thing is tiny. It’s funny I knew it was small, but it still amazes me that you can squeeze effectively a small computer in the space of a couple of postage stamps.
- The fit and finish seems pretty good for a $3 board. What an age we live in!
- Loading Micropython took longer than it should have but that may have been user error. This tutorial is pretty good.
- The LED turns on when the pin is low and off when the pin is high. Huh?
- Micropython is pretty awesome so far. I’m sure Arduino is more efficient but with 160 Mhz of process power and a couple of megs of space, I’m not worrying!
- Connecting with screen works but not picocom? Weirdness.
- The machine library in MicroPython is pretty handy, a good replacement for a lot of the Arduino built-ins.
- There is no consensus about how to capitalize Micropython. Is it micropython, Micropython, MicroPython, etc. This frustrates the copy editor in me.
- Wait… do I just pull the plug to turn this thing off? That feels wrong but I guess it is what I always did with my other ESP8266 boards… But it feels weird not to shut down something that has an interactive prompt.
Alright, those are some quick thoughts, more later.
