TVS diode (D1) protects the V

BUS

power line and, consequently, the entire system against

electrical overstress (EOS) when you connect a sink through the USB Type-C™ cable.
To be compliant with the USB Power Delivery standard requirements, the board embeds the 330 pF C1 and C2
capacitors, as well as the 2.2 µF C13 capacitor, which ensures a good system robustness.

1.2.2

USB 2.0 data path and configuration settings

The

X-NUCLEO-SRC1M1

expansion board allows the

development boards that feature a USB 2.0

peripheral to expose the D+/D- lines on the USB Type-C™ receptacle (CN1).
Most STM32 Nucleo-64 development boards feature this functionality on the CN10-12 and CN10-14 pins of
the ST morpho connectors. The

NUCLEO-L412RB-P

,

NUCLEO-L433RC-P

NUCLEO-L452RE-P

development boards, instead, map USB 2.0 data on CN10-33 and CN10-17 pins.

Two couples of resistances are connected to the

(U3) USB 2.0 data line protection to extend the

use of this peripheral to all the STM32 Nucleo-64 development boards.
