ARM Cortex-M3 info

ARM Cortex-M3
Core103V is an STM32 development card that can be expanded in small sizes using the STM32F103VET6 as a microcontroller. It is ideal to start developing applications with the STM32F family. It uses the Core103V USB communication interface as a system ready to run with little effort, combining features such as JTAG / SWD programming / debugging interface, 8I / Os and UART1 test interfaces, clock circuit, USB power management, boot mode selection.
