Sorta tempted to do something similar in arduino-land to solve a processing problem I am having...

  Use a http://www.mouser.com/ProductDetail/STMicroelectronics/STM32F4DISCOVERY/?qs=sGAEpiMZZMutVogd4PRSvEN8XDBeCtgD http://www.mouser.com/ProductDetail/STMicroelectronics/STM32... instead of arduino, 192k of ram and a floating point unit.

    Floating point is exactly the problem. I am building a balancing robot. What's the tool chain like?

      I've used the Keil IDE, which is free for small projects. Takes some getting used to but great debugger and easy to get started. There's also free Eclipse/gcc toolchains so if you're already used to Eclipse that's an easy way to get started. All the newer ST demo boards have on-board JTAG debuggers so they're a little bigger but convenient since you just need a USB cable. External JTAG debuggers are pretty cheap and Keil (ARM) has a super-nice trace probe if you're willing to spend a little more.

      I have no idea if it would be appropriate for your build, but the previously featured micropython (board) does have an fpu (and "oodles" of processing power) https://github.com/micropython/micropython/wiki https://github.com/micropython/micropython/wiki [Oh, same series - same chip? Very similar anyway]

    Maple might be a good option too; Arduino-style STM32! http://leaflabs.com/devices/ http://leaflabs.com/devices/

      Great for Arduino compatibility but those don't have floating point units.
