Step 5: Package Contents
The unzipped package contains a DOC directory, ready-to-use binary files, associated project files, and compliance reports.
Suggested Hardware Requirements
The software library is optimized for compilation on the NUCLEO-F446FE development board when stacked with the MB1303 expansion board (available via the P-NUCLEO-USB002 package).
The MB1303 expansion board features 2 Dual Role Ports (DRP) capable of USB Power Delivery (PD) communication, though its form factor is not optimized.
Hardware Components:
- NUCLEO-F446ZE: This is the STM32 Nucleo-144 development board.
- MB1303: This is the STUSB1602 Nucleo Pack, which includes the MB1303 shield. It is provided as part of the P-NUCLEO-USB002 orderable package and is designed to be plugged onto the NUCLEO-F446ZE.
Two development boards are presented. The board on the left is identified as NUCLEO-F446ZE. The board on the right is labeled MB1303 and is described as being contained within the P-NUCLEO-USB002 orderable package.
NUCLEO-F446ZE Hardware Set-up
The following hardware modifications are recommended for the MB1137 board to effectively utilize the MB1303 shield offering, which provides 2 USB PD ports based on STUSB1602 and STM32F446ZE:
Modifications:
Remove Components:
- SB118
- SB5
- SB6
- R37 (for 2nd port LEDs)
- R38 (for 2nd port LEDs)
Close Components:
- SB144 (for 2nd port LEDs)
- SB145 (for 2nd port LEDs)
Add Components:
- 38-pin connectors on both CN11 and CN12.
For Trace:
- Add a wire connection between PA9-CN9 (pin21) of the MB1303 board and CN5-RX on the Nucleo-MB1137 board.
Software Package Overview
The software library comprises 8 distinct software frameworks, with an additional 3 available without RTOS support. These are all optimized to address common application scenarios.

|---|---|
| STM32F446_MB1303_SRC_ONLY(*) | Provider / SOURCE (power management) |
| STM32F446_MB1303_SRC_VDM | Provider / SOURCE (power management) + extended message support |
| STM32F446_MB1303_SNK_ONLY(*) | Consumer / SINK (power management) |
| STM32F446_MB1303_SNK_VDM | Consumer / SINK (power management) + extended message support + UFP support |
| STM32F446_MB1303_DRP_ONLY (*) | Dual Role Port (power management) + dead battery mode |
| STM32F446_MB1303_DRP_VDM | Dual Role Port (power management) + dead battery mode + extended message support + UFP support |
| STM32F446_MB1303_DRP_2ports | 2 x Dual Role Port (power management) + dead battery mode + extended message support + UFP support |
| STM32F446_MB1303_DRP_SRCING_DEVICE | Dual Role Port requesting PR_swap when attached in Sink or DR_swap when attached in Source |
Note: By default, all projects are packaged with RTOS support. Projects annotated with an asterisk (*) are available with and without RTOS support.
