Note: 
The Open103C supports programming via STM32 USART bootloader, a USB TO UART accessory board is also provided in the package. 
The Open103C does NOT integrate any debugging function, a debugger is required.
The Open103C Standard includes only ONE accessory board -- PL2303 USB UART Board (mini).
