[Matt Evans] took a closer look at the popular (and cheap) STM32F0 Discovery development board and realized he could get a second board out of the deal (http://www.axio.ms/projects/stm32-241/) .The Discovery board is designed to advertise ST Microntroller's STM32F0 microchip; which with 8k RAM, 64K Flash, a bunch of peripherals, 48MHz clock, and a low price is a great chip. Though, they needed a way to program the STM32F0. To do this they added a second, more powerful, chip to the board as an interface. The STM32F103, with 20k RAM, 64K flash, and a 72MHz clock speed. [Matt] summoned genius, and simply sawed the board in half using a hacksaw.Of course the caveat to all this is that you need a working Discovery board, or at least a working ST-LINK programmer, at the end of the day, to get any use out of your creation. Since the boards are so cheap though, it shouldn't be a problem to buy two.
