P-NUCLEO-USB002 expansion board
The P-NUCLEO-USB002 expansion board consists of different stages for specific aspects
of the power delivery protocol. It embeds two USB Type-
C™ ports, each containing the
following functional blocks:
an STUSB1602 Type-C port controller
V
BUS
management stage
voltage and current measurement circuitry
a V
CONN
selector
status LEDs
ESD protections
The P-NUCLEO-USB002 expansion board local voltage regulator interacts with both of
V
BUS
