It turns out that this processor is also suitable for running MicroPython on, so you will see MicroPython ported to this very shortly after its released.
There is 4 days left in the Kickstarter campaign.
Disclaimer: I signed up for the Ultimate Toy Kit.
I also have a few (3) of the original Espruino boards that I’m not using, and if anybody would like to play with one, let me know. I wound up getting hooked on MicroPython instead.
