I remember being unable to find the max current per pin on an STM32F1 datasheet (for the original Espruino). Like, is it "you can try to draw as much current as you want from a pin, but the most you'll get is 20mA or so"? On the AVR's in arduino-land, there's a max recommended current per pin, and an absolute max current per pin (which will be exceeded if you short a pin to ground and try to drive it high, for example).
I think it would be a very good idea to find that spec for the official espruino boards at least, and list it clearly on the reference pages.
