6  Hardware layout and configuration
The STM32 Nucleo-64 boards are designed around the STM32 microcontrollers in a 64-pin 
LQFP package.
Figure 2 illustrates the connections between the STM32 and its peripherals (STLINK/V2-1, 
pushbutton, LED, and morpho connectors).
Figure 3 and Figure 4 help the user to locate these features on the STM32 Nucleo-64 board.
