STM Nucleo- F103RB board is a Medium-density high performance full scale evaluation platformsupported with ARM32-bit MCU and 64 or 128 KB Flash, USB, CAN, 7 timers, 2 ADCs, 9 communication interfaces. STM32 Nucleo is an ideal solution for low cost development platform in LQFP64 package. The board offers two types of extension resources Arduino Uno V3 connectivity and ST morpho extension pin headers for full access to all STM32 I/O s with ARM mbed enabled for the support of online tools providing open source development platform. The STM32 Nucleo boards integrate an ST-Link debugger/programmer with separate selection-mode switch which enable the board to be used as a standalone ST-LINK/V2-1. STM32 Nucleo boards can be used with wide range of development environments including IAR EWARM, Keil MDK-ARM, mbed and GCC/LLVM-based IDEs and finds integrated solution for the automation and control devices like PLC, HVAC, handheld equipment.
