STM32F103-based extendible motherboard

The STEVAL-IDX001V1 demonstration board is based on the STM32F103RET6 micro with 512 kB of Flash and 64 kB of RAM. It has been designed to be easily extended with daughterboards that can be piled up by means of the integrated 20-pin and 25-pin connectors. These connectors mainly export the GPIOs of the micro and other board system signals. The micro can be programmed and debugged via the JTAG and the USB connectors that are also integrated. The STEVAL-IDX001V1 demonstration board allows different power supply options. Configurable LEDs and pushbuttons are integrated to allow user interaction at the run time. Onboard jumpers allow the configuration of the micro boot mode, the power source and the USB interface for connection with a PC. In particular, the use of the USB requires the installation of the driver of the RS-232 SiLab CP2102 bridge while the use of the mini-USB requires the installation of the STM32F USB driver available from the ST website.
