Oh damn.

That's actually the page I was reading, I didn't notice the 'M' in there.

I like the task. You had me at 'this is a huge change...' in your
first email. Whether I have the ability is yet to be seen. Thanks for
the offer of the card, let's wait first to see if I can make any
progress that warrants testing. The new breakout board turned up in
the mail today, super glad to read your email before I spent the day
tomorrow trying to get it working :)
