According to...
https://github.com/micropython/micropyt ... duinoPlus2
...the Netduino Plus 2 runs micropython.
The page at...
https://www.wildernesslabs.co/Netduino
...says that there are three Netduino 3 models available, and...
https://en.wikipedia.org/wiki/Netduino#Netduino_2
...says that they have the same Cortex-M4 @ 168 MHz as the Netduino 2 plus with more flash and more RAM.
So, can I run micropython on a Netduino 3 or should I stick with the Netduino 2 plus?
