6 Hardware layout and configuration
The STM32 Nucleo board is designed around the STM32 microcontrollers in a 64-pin LQFP
package.
Figure 2 shows the connections between the STM32 and its peripherals (ST-LINK/V2-1,
push-button, LED, ARDUINO
®
connectors, and ST morpho connector).
Figure 3 and Figure 4 show the location of these features on the STM32 Nucleo board.
Figure 5 shows the mechanical dimension of the STM32 Nucleo board.
