Getting started with the X-NUCLEO-SNK1M1 USB Type-C® Power Delivery Sink
Introduction
The X-NUCLEO-SNK1M1 expansion board allows evaluating the features of TCPP01-M12 and the USB Type-C® overvoltage
protection for V
and CC lines suitable for Sink applications.
BUS
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
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).
Note:
Before running any demo, set CC1 J1, CC2 J2, JP3 and JP4 jumpers according to the configuration described in
Section 1.3 Demo application

    CC lines and configuration jumpers Two headers for jumpers (J1 and J2) have been integrated to change the CC lines paths from the TCPP01-M12 protection to the ST morpho connectors (CN7 and CN10) on the STM32 Nucleo development board, setting them differently according to the peripheral mapping of the STM32 microcontroller.
