* @brief Nucleo board file
* edited and tested by Matthias Diro, Release Date: 27.01.2015
* there are some solderings neccessary for complete compatibility
* consider the Nucleo User manual for:
* OSC clock: clock must be driven either from "MCO from ST-Link" or Oscillator from external PF0/PD0/PH0. Soldering is neccessary if board number is MB1136 C-01, see -> 5.7 OSC clock
* USART: If PA2/PA3 needed, solder bridges must be changed. see -> 5.8 USART communication
