[rant]Designed without target audience in mind.
90% of ill artistic vision and 10% of engineering effort.
Because of some reason they made it small. Now what are kids supposed to do with that, without a laboratory equipment? Does it come with some base-board with edge connector that mates with the PCB?
Their idea was to make IOs crockodile-friendly??
Does it come with a bunch of clips at least?
Also loading that PCB with components on both sides prohibits its use in a flat desk environment, without the easy option to stick it with a tape. Not mentioning double sided is much more expensive in production and testing.
Next silly thing is that the prone for break-off micro-USB in the SMD version is used
I like the idea this is a combined global effort of the companies but I seriously doubt a teenager is going to like an embedded C or ARM assembler. I'd suggest something easier, higher level language that can run on both x86 and the thingy, like java or maybe even MATLAB/Simulink-ish (graphical programming).
Mind debugging CM0 is not a trivial task so maybe the board is intended to serve only as simple BLE IO card and custom code is executed on a remote x86 host..
