P-NUCLEO-USB002 expansion board: USB Type-C connectors, 
voltage and current sense stage 

The two USB Type-

C™ CN0 and CN1 connectors on the P-NUCLEO-USB002 expansion 

board represent port 0 and port 1 respectively. 

When a port acts as a power provider, it can supply an external device connected via a 
USB Type-

C™ cable; the same port can receive power if it is set as a consumer.
