ST STM32G4 Nucleo-64 User Manual

6 Hardware layout and configuration
The STM32G4 Nucleo-64 board is designed around the STM32 microcontrollers in a 64-pin LQFP package.
Figure 3 shows the connections between the STM32 and its peripherals (STLINK-V3E, push-buttons, LEDs, USB,
Arduino
™
Uno and ST morpho headers). Figure 4 and Figure 5 show the location of these features on the
STM32G4 Nucleo-64 board. The mechanical dimensions of the board are shown in Figure 6.
