X-NUCLEO-SNK1M1

X-NUCLEO-SNK1M1 expansion board allows evaluating the features of TCPP01-M12 and the USB Type-C overvoltage protection for VBUS and CC lines suitable for Sink applications. The expansion board is designed to be stacked on top of any STM32 Nucleo-64 development board exploiting the characteristics of the USB Type-C and Power Delivery (UCPD) peripheral embedded in their microcontrollers. It can also be stacked on other STM32 Nucleo development boards not supporting the UCPD peripheral to demonstrate the Type-C basic operations (attach, detach and power supply current capability recognition). The X-NUCLEO-SNK1M1 provides an effective demonstration of the dead battery operation, thanks to the integrated ST715PU33R LDO linear regulator that supplies the connected STM32 Nucleo development board when a Source is attached via a USB Type-C connector.
