What baud rate does it run at?

115200 by default (it's what iBoot initializes it at), but I spent a chunk of yesterday's live development stream yak-shaving a way to smoothly switch to 1.5Mbaud in a way that lets my Glasgow-based auto-baud-sensing serial interface resync cleanly (turns out: it seems to be impossible using any single byte repeating with 1 stopbit and no pauses due to ambiguous framing; I had to use a multiple-byte pattern).

115200 by default

This made me laugh because I spent a good chunk of last weekend trying to debug a problem with some of my old computer hardware and the problem turned out to be a link that couldn't handle anything over 150 baud.

Now we're squirting 115,200 straight out of a chip. It's like the future!

The crazy part is that 115200 is actually slow by today’s standards!
