2Board component description and configuration
2.1 Connectors
The X-NUCLEO-USBPDM1 expansion board is equipped with USB Type-C™ connector (CN1).
VBUS can supply:
• the power connector (CN2) in normal mode
• STM32 when LDO (U2) output is connected to 3.3 V pin
2.2 Jumpers
To select the STM32 Nucleo development board to be used with the X-NUCLEO-USBPDM1 expansion board,
use JP1 jumper (UCPD peripheral selection) and CC lines (CC1 and CC2) connection:
•For the NUCLEO-G071RB development board, use STM32 UCPD transceiver CC lines connection to ST
morpho connector (CN10–23 and CN10–26).
• For the NUCLEO-G474RE development board, use STM32 UCPD transceiver CC lines connection to ST
morpho connector (CN10–17 and CN10–27).
Other connections among the two boards are configured by JP2 jumpers.
The global jumper setup is the following:
•LDO OUT – 3.3 V to connect the LDO output to 3.3 V on the X-NUCLEO-USBPDM1. The STM32 is
powered by the USB Type-C connector.
Note: In this mode, the only way to program the STM32 Nucleo development board is to power the ST-LINK and
disconnect the LDO output.
•3.3 V is common between X-NUCLEO-USBPDM1 and STM32 Nucleo development boards.
•3.3 V – NRST to force the STM32 I/O negative reset to level ‘1’. It must be connected when the STM32 is
powered by the X-NUCLEO-USBPDM1 and when the STM32 Nucleo development board ST-LINK is
connected. When programming or when ST-LINK is physically disconnected from the STM32 Nucleo
development board, 3.3 V – NRST must be disconnected.
•FLT – FLT_IN to connect the TCPP01-M12 fault report (open drain) to a pull-up output and to the ST
morpho connector (CN10 – 18, PC0 of NUCLEO-G071RB and PB11 of NUCLEO-G474RE).
The TCPP01-M12 supply options are:
•VCC – 3.3V to supply the TCPP01-M12 VCC with 3.3 V.
•VCC – VCC_OUT to supply the TCPP01-M12 VCC via a GPIO on ST morpho connector (CN7 – 1, PC10 of
NUCLEO-G071RB and NUCLEO-G474RE). This case is useful with battery powered devices as the
TCPP01-M12 can be powered only when an attachment is detected (low power mode).
• Integrated dead battery management for fully depleted battery devices.
Dead battery management options are:
•DB – 3.3 V to remove the TCPP01-M12 dead battery clamp when 3.3 V is present.
•DB – DB_OUT to remove the TCPP01-M12 dead battery clamp when GPIO is connected on ST morpho
connector CN10 – 24. In this case, the STM32 MCU manages dead battery clamp removal.
2.3 LEDs
Two LEDs are mounted on the X-NUCLEO-USBPDM1 expansion board top side:
•A red LED to indicate the USB Type-C VBUS voltage is present (voltage on CN2 and LDO powered).
• A green LED to indicate that 3.3 V is present and can be supplied by the STM32 Nucleo development board
or by the X-NUCLEO-USBPDM1 LDO.
2.4 VBUS overvoltage protection setup
On the X-NUCLEO-USBPDM1 expansion board bottom side, a zero Ohm resistor (R0) selects a 22 V OVP
threshold.
UM2668
Board component description and configuration
UM2668 - Rev 2 page 4/19

To change the threshold to another value (6 V, 10 V, 13 V or 17 V), R0 must be removed and a solder bridge must
be added on the selected OVP voltage.
2.5 USB Type-C D+/D- connections
On the X-NUCLEO-USBPDM1 expansion board bottom side, D+/D- lines from USB Type-C CN1 are connected to
D+/D- lines of the NUCLEO-G474RE development board thanks to R8 and R9 zero Ohm resistors. These lines
can be used for USB BC 1.2 check and data transmission.
There is no USB data on the NUCLEO-G071RB but USB BC 1.2 check can be done thanks to STM32G071RB
PA4 (CN7 – 32) and PA5 (CN10 – 11): zero Ohm resistors R8 and R9 must be unsoldered and zero Ohm
resistors must be soldered on R10 and R11 footprints.

3Programming and debugging
For programming and debugging, the X-NUCLEO-USBPDM1 expansion board must be powered by the STM32
Nucleo development board.
JP2 LDO OUT – 3.3 V and 3.3 V – NRST pins must be removed.
TCPP01-M12 can be powered by one of the following options:
• the STM32 Nucleo 3.3 V (JP2 Vcc – 3.3 V jumper close and VCC – V_OUT jumper open)
• a dedicated STM32 GPIO for battery powered cases (JP2 VCC – 3.3V jumper open and VCC – V_OUT
jumper closed). This case is also called low power mode.
TCPP01-M12 dead battery resistor clamps are removed:
• automatically when 3.3 V is present (JP2 DB – 3.3 V jumper closed and DB – DB_OUT open)
• or by a GPIO (JP2 DB – 3.3 V jumper open and DB – DB_OUT closed)

4USB Type-C powered mode
Once STM32 is programmed, it is possible to power the STM32 using USB Type-C VBUS voltage through a
source device connected to the Type-C connector (CN1). The X-NUCLEO-USBPDM1 on-board LDO (U2)
generates 3.3 V to supply the system. In this case, 5 V is not available yet on the STM32 Nucleo development
board.
Note: STM32 Nucleo development board power jumper must not be connected (JP2 of NUCLEO-G071RB or JP5 of
NUCLEO-G474RE).
JP2 LDO OUT–3.3 V and 3.3 V–NRST jumpers must be closed.
TCPP01-M12 can be powered by:
• 3.3 V from the USB Type-C connector VBUS (JP2 Vcc – 3.3 V jumper closed and Vcc–V_OUT jumper open)
or
• a dedicated STM32 GPIO for battery powered cases (JP2 Vcc – 3.3 V jumper open and Vcc–V_OUT
jumper closed). This case is also called low power mode.
TCPP01-M12 dead battery resistor clamps are removed:
• automatically when 3.3 V is present (JP2 DB – 3.3 V jumper closed and DB – DB_OUT open) or
• by GPIO (JP2 DB – 3.3 V jumper open and DB – DB_OUT closed).

5NUCLEO-G474RE Type-C powered mode Sink contract negotiation
In this case, dead battery clamps are removed when 3.3 V jumper is connected (not in low power mode).
NUCLEO-G474RE must be powered by ST-LINK micro-USB connector (JP5 5V_STLK jumper closed).
Step 1. Connect the NUCLEO-G474RE micro-USB connector (CN1) to your PC.
NUCLEO-G474RE appears as a virtual disk (NODE_G474RB).
Step 2. To program the STM32G474RE, drag and drop the binary file corresponding to the required voltage
(G474RE_TCPP01_no-low-power_no-DB-mng_SNK_xxV_v1.bin, xx is the selected voltage) to
the virtual disk.
LD1 blinks red and green for few seconds. When it does not blink any more, programming is complete.
Step 3. Plug the X-NUCLEO-USBPDM1 expansion board on top of the NUCLEO-G474RE development board.
Step 4. On X-NUCLEO-USBPDM1 JP1, close CC1_G4 and CC2_G4, and leave the other jumpers open.
Step 5. On X-NUCLEO-USBPDM1 JP2, close Vcc–3.3 V and DB–3.3V and leave the other jumpers open.
X-NUCLEO-USBPDM1 CN1 (USB Type-C receptacle) can be connected to any Type-C source. The X-
CUBE-USBPDM1 selects the highest and closest power profile to the value indicated by the binary file
from available power profiles on the source. The obtained voltage can be measured on X-NUCLEO-
USBPDM1 CN2.
Step 6. Disconnect the micro-USB cable from NUCLEO-G474RE CN1 and the USB Type-C cable from X-
NUCLEO-USBPDM1 CN1.
Step 7. Remove the power supply from NUCLEO-G474RE (JP5 fully open).
Step 8. On X-NUCLEO-USBPDM1 JP2, close LDO OUT 3.3 V, 3.3 V–NRST, Vcc–3.3 V and DB – 3.3 V and
leave the other jumpers open.
As previously mentioned, X-NUCLEO-USBPDM1 CN1 (USB Type-C receptacle) can be connected to
any Type-C source. The X-CUBE-USBPDM1 selects the highest and closest power profile to the value
indicated by the binary file from available power profiles on the source. STM32G474RE is then
powered by Type-C connector and X-NUCLEO-USBPDM1 can be fine tuned with VBUS OVP voltage
selection thanks to R0 position change. This configuration is relevant for a Type-C powered device
without battery as it is not in low power mode (Vcc is directly connected to 3.3 V). The data lines of
Type-C connector CN1 are connected to the STM32G474RE USB 2.0 full-speed transceiver thanks to
R8 and R9 zero Ohm resistors.

6NUCLEO-G071RB Type-C powered mode Sink contract negotiation
In this case, dead battery clamps are managed by STM32G071RB in low power mode.
NUCLEO-071RB must be powered by ST-LINK micro-USB connector (JP2 STLK jumper closed).
Step 1. Connect the NUCLEO-071RB micro-USB connector (CN1) to your PC.
NUCLEO-071RB appears as a virtual disk (NODE_G071RB).
Step 2. To program the STM32G071RB, drag and drop the binary file corresponding to the required voltage
(G071RB_TCPP01_low-power_no-DB-mng_SNK_xxV_v1.bin, xx is the selected voltage) to the
virtual disk.
LD1 blinks red and green for few seconds. When it does not blink anymore, programming is complete.
Step 3. Plug the X-NUCLEO-USBPDM1 expansion board on top of the NUCLEO-071RB development board.
Step 4. On X-NUCLEO-USBPDM1 JP1, close CC1_G0 and CC2_G0, and leave the other jumpers open.
Step 5. On X-NUCLEO-USBPDM1 JP2, close Vcc–Vcc_OUT and DB-DB_OUT and leave the other jumpers
open.
X-NUCLEO-USBPDM1 CN1 (USB Type-C receptacle) can be connected to any Type-C source. The X-
CUBE-USBPDM1 selects the highest and closest power profile to the value indicated by the binary file
from available power profiles on the source. The obtained voltage can be measured on X-NUCLEO-
USBPDM1 CN2.
Step 6. Disconnect the micro-USB cable from NUCLEO-071RB CN1 and the USB Type-C cable from X-
NUCLEO-USBPDM1 CN1.
Step 7. Remove the power supply from NUCLEO-071RB (JP2 fully open).
Step 8. On X-NUCLEO-USBPDM1 JP2, close LDO OUT 3.3 V, 3.3 V–NRST, Vcc–Vcc_OUT and DB-
DB_OUT and leave the other jumpers open.
As previously mentioned, X-NUCLEO-USBPDM1 CN1 (USB Type-C receptacle) can be connected to
any Type-C source. The X-CUBE-USBPDM1 selects the highest and closest power profile to the value
indicated by the binary file from available power profiles on the source. STM32G474RE is then
powered by Type-C connector and X-NUCLEO-USBPDM1 can be fine tuned with VBUS OVP voltage
selection thanks to R0 position change or via USB BC 1.2 check on source (short on D+/-) thanks to
R8 and R9 zero Ohm resistor position change to R10 and R11 positions.
This configuration is relevant for a battery-powered device thanks to the low power mode (Vcc
connected to GPIO). This results in zero power consumption for the TCPP01-M12 when the Type-C
cable is unplugged.
