The STM32F0308 Discovery board is shipped pre-configured and ready to use out of the box. Powered from a USB socket or separate power supply, the kit has an extension header allowing quick connection to all microcontroller I/Os. The onboard 64-pin STM32F030R8T6 microcontroller features 64 kB Flash memory and 8 kB RAM.
The STM32F030 Value Line microcontroller family, ST says, obsoletes the minimalist approach traditionally imposed on low-end embedded designs. By relieving the resource constraints familiar to 8-bit users, this family streamlines design, boosts application performance, and allows scalability with minimal hardware changes. The devices feature a 48MHz ARM Cortex-M0, 5-channels DMA, core and versatile peripherals such as a motor-control timer, five general-purpose timers and a 1 Msample/sec 12-bit ADC, to offer performance at price parity with older 8-bit architectures. STM32F030 Value Line devices are supported by 100% free development toolchains, in addition to the low-cost discovery kit and generic tools supporting ARM Cortex-M devices.
