ST STM32 Nucleo User Manual

6 Hardware layout and configuration
The NUCLEO-C031C6 Nucleo-64 board is designed around the STM32C031C6T6 microcontroller in a 48-pin
LQFP package.
The hardware block diagram in Figure 2 illustrates the connections between the NUCLEO-C031C6
microcontroller and its peripherals, such as the ARDUINO
®
Uno V3 connector, ST morpho connector,
push‑button, and embedded ST-LINK/V2-1).
Figure 3 and Figure 4 help the user to locate these features on the STM32 Nucleo-64 board. The mechanical
dimensions of the NUCLEO-C031C6 product are shown in Figure 5.
