The table below shows the jumper settings to configure the X-NUCLEO-SNK1M1 to work with the STM32 Nucleo
development boards embedding the UCPD peripherals ( NUCLEO-G071RB and NUCLEO-G474RE ) as well as
with other STM32 Nucleo-64 boards ( NUCLEO-L412RB-P ) implementing the Type-C attach-detach recognition
mechanism.

When both configuration jumpers (J1 and J2) are set to positions 1-2, the board is compatible with NUCLEO-
G071RB and NUCLEO-G474RE offering the UCPD peripheral.
This association permits to fully demonstrate the main characteristics of the USB Type-C and Power Delivery
standards implemented by the demo application example.
When J1 and J2 are both set to positions 2-3, the
X-NUCLEO-SNK1M1 can match any STM32 Nucleo-64
development board, demonstrating the basic mechanism of the Type-C specification, thanks to two pull-down
resistors (R17 and R21) connected to the pins working as CC lines, allowing the Sink Type-C operations to run
with any attached Source.
