I’ve recently discovered the stm32-discovery board from STMicroelectronics thanks to someone at work. ┬áIt’s quite an impressive device (the STM32F100RB onboard, that is), but not as easy to use out of the box as an Arduino.

I bought two from mouser at $11 a piece….expect to see several upcoming posts related to this little board.
