6 Hardware layout and configuration
The STM32 Nucleo-144 board is designed around the STM32 microcontrollers in a 144-pin
LQFP package.
Figure 3 shows the connections between the STM32 and its peripherals (ST-LINK/V2-1,
push-buttons, LEDs, USB, Ethernet, ST Zio connectors and ST morpho headers).
Figure 4 and Figure 5 show the location of these features on the STM32 Nucleo-144 board.
The mechanical dimensions of the board are shown in Figure 6 and Figure 7.
