Quick delivery. Very useful for multiple analogue inputs. Would be useful to have the option of an un-soldered header, and supplied with spare/loose straight and right-angled headers for end-user soldering (some of us "old school" types don't mind a bit of soldering :-)

Dans la même veine que les autres beakouts. Tres pratique à l'usage et la conception est parfaite.

Great little board, I wish there was a Node-Red node to control it rather than having to revert to a Python node in Node Red. Not knowing Python it took me a little while to get my head around it.

I'm using this to replace an I2C Itsy Bitsy M4 Express working as a master-slave handling sensor inputs on a Raspberry Pi based robot, and it was (rather obviously) a lot easier to set up, and while I like using the Itsy Bitsy, which has a 120MHz clock, I was surprised to find that the performance was about twice as good, about 85ms to read eight analog and digital pins, whereas the Itsy Bitsy was doing that at about 173ms. All in all this board is a success. My only criticism is that it'd be nice if the header was either not already soldered on (though I realise some people would prefer that), or was available with that option. If I'd had the option I'd probably have used a right angle header but it is a minor beef. It would be really great if someone from Pimoroni would flesh out a python example of using the Nuvoton MS51 microcontroller for some other purpose, there seems to be huge possibility there, like using the MS51 as a controller in its own right since it's already on the I2C bus.

Nice breakout! Your python-code makes the difference. One thing to note though: the holes of the I2C-connector don't properly line up. Maybe this is on purpose, but in this case it would have made more sense to let the already soldered pins face to the other side.
