smart and loveable little chip
For PicoPlanet
Thought out and lovely little product. Fast shipping and although there is no documentation in the package, you will find most stuff in the git repository - a link + qr code is included.
I had no real problems with PicoPlanet itself, only with how to setup my dev environment. This was my first try with python and working with microcontrollers, so I can't blame PicoPlanet for that.
Of course you will need a bit of programming experience, so for absolute beginners I would recommend a more powerful product to play with. But given the restrictions by design, you're getting a toughtful piece of art to play with.
