Product overview


The X-NUCLEO-SRC1M1 expansion board allows evaluating the features of the TCPP02-M18 for the USB Type-C™ and the protections for VBUS and CC lines suitable for source applications.

The expansion board is designed to be stacked on top of any STM32 Nucleo-64 development board with Power Delivery (UCPD) peripheral embedded in the microcontroller.

You can also stack it on top of any other STM32 Nucleo-64 development board not supporting the UCPD peripheral for 5 V, source only, to demonstrate the USB Type-C™ basic operations (attach, detach and 5 V power supply current capability information).

When using an STM32 Nucleo-64 development board with a Power Delivery peripheral, data functionalities as a host device or dual role data (DRD) are also allowed.

The X-NUCLEO-SRC1M1 provides an effective demonstration of the source operation of the USB Type-C™ connector when an external compatible source is connected to the board. The integrated ST715PU33R LDO linear regulator can supply the connected STM32 Nucleo development board.

The X-NUCLEO-SRC1M1 is compliant with the latest USB Type-C™ and Power Delivery specifications.

The companion software package (X-CUBE-TCPP) contains the application examples for the development boards embedding UCPD-based microcontrollers (for example, NUCLEO-G071RB, NUCLEO-G474RE, and NUCLEO-G0B1RE) and for those not supporting the UCPD peripheral (NUCLEO-F446RE).
