The STM32 G4 family is a modern and powerful MCU family. Many chips include a dedicated USB PD peripheral (called UCPD) and thus require no additional hardware.
- Nucleo-G431KB
- Nucleo-G474RE
No additional components needed.
Optionally, the X-NUCLEO-SNK1M1 shield can be used for the Nucleo-G474RE.
