X NUCLEO SNK1M1
The expansion board (shield) for Nucleo boards in the Nucleo-64 form factor provides the separate USB-C connector.
Additionally, it uses the TCPP01-M12 port protection chip. The chip needs to be configured. Otherwise, it will block the CC1/CC2 signals. See below for details.
- Nucleo-G071RB
- Nucleo-G474RE
Jumpers JP1 and JP2 should be set to 1–2 position (CC1_Gx/CC2_Gx). Jumpers JP3 and JP4 should not be set.
To initialize the port protection chip, add this code to your setup() function:
NucleoSNK1MK1.init();The below STM32 pins are hardwired by the shield and cannot be used otherwise unless solder bridges and 0 Ω resistors are changed.
DB_OUT and VCC_OUT are used to control the TCPP01-M12 port protection chip.
