Hardware layout and configuration
The STM32G4 Nucleo-32 board is designed around the STM32 microcontrollers in a 32-pin UFQFPN package.
shows the connections between the STM32 and its peripherals (STLINK-V3E, push button, LEDs, USB
and Arduino Nano).
show the location of these features on the STM32G4 Nucleo-32 board.
The mechanical dimensions of the board are shown in
