7.17 GPIO expansion connectors
7.17.1 Description
• The GPIO pins can be used as GPIOs or alternate functions. The available alternate functions are listed in
Table 25. GPIO connectors pinout.
• Other functions such as I
2
C, UART, or FDCAN can be mapped on the GPIO connectors, for instance using
the STM32CubeMX tool.
• The GPIO expansion connector CN2 offers Raspberry Pi
®
shields capability.
7.17.2 GPIO expansion connector interface
Figure 17 shows the pinout of the GPIO connectors.
