The 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 USB 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.
The X-NUCLEO-SNK1M1 is compliant with the latest USB Type-C® and Power Delivery specifications and is also USB-IF certified as a 100 W solution supporting Programmable Power Supply (PPS) function.
The companion software package (X-CUBE-TCPP) contains the application examples for development boards embedding UCPD-based microcontrollers (NUCLEO-G071RB, NUCLEO-G474RE and NUCLEO-G0B1RE) and for non-UCPD ones (NUCLEO-L412RB-P).
