This is super tempting @ $24. As someone who is not used to
tinkering with raw hardware, how does one power this thing?
I've tinkered with SBCs, but those had full-blown Linux. What
hardware is necessary to get this thing running?

It's powered from your PC's USB port (Using one right now,
actually). No extra hardware is needed unless you want to add
features beyond what the board provides. Due to its large number
of pins, and the way they are arranged, they don't plug into
breadboards, but you can easily use jumper wires for that:

I have a basic D demo for this board here:
https://github.com/JinShil/stm32f42_discovery_demo. It's just a
blinky app at the moment, but it does all the work of configuring
the clocks, flash, etc... before calling the "main" function.
There's quite a few "Discovery" boards from ST

as well as boards from other manufacturers
(http://www.mikroe.com/stm32/development-boards/).
It's quite exciting to see Jens's work and the expressed interest
in using D for this domain. I hope to see more.
