Note:
6.4.2
When the board works abnormally, power it from a source capable of supplying a higher current.
STLK (for compatibility with legacy USB Host port)
Figure 8 shows the 5V selection from STLK on JP1, with a power source connected to USB ST-LINK (CN7). It is
the default setting.
The CN7 ST-LINK USB Type-C® connector (STLK) can power the STM32H7S78-DK Discovery kit, but the host
PC only provides 100 mA to the ST-LINK circuit until the end of the USB enumeration. At the end of the USB
enumeration, the STM32H7S78-DK Discovery kit requests a 500 mA current from the host PC.
If the USB enumeration succeeds, a power switch powers the board with a current of up to 500 mA. This power
switch also features a 700 mA, 1.8 A, or 3.5 A current limitation. This protects the PC in case of overcurrent on the
board.
Note:
In this mode, in case a wall charger powers the board, there is no USB enumeration. Therefore, the COM LED
(LD7) remains OFF permanently. Anyway, the 700 mA (or 1.8 A or 3.5 A) protection is still active on the powered
board.

5VIN
Figure 9 shows the 5 V DC power selection from 5VIN on JP1. The power source is connected to the external VIN
on CN12 pin 8 VIN. It is then used by an embedded LDO to generate the 5V_VIN power supply. In this case, a
power supply unit or auxiliary equipment complying with the standard EN 62368‑1:2014/A11:2017 must power the
STM32H7S78-DK product. It must also be a safety extralow voltage (SELV) with limited power capability.
Note:
There is no input current protection in this configuration. The recommended maximum current to be drawn from
this E5V pin is 800 mA. This depends on the VIN source voltage and capability.
Figure 9. JP1 (5VIN) from CN12 (VIN)
6.4.4
User USB2
Figure 10 shows the selection of 5 V DC power from user USB2 on JP1, with a power source connected to the
USB Type-C® connector (CN17). A power switch with TCPP01-M12 circuit is protecting the STM32H7S78-DK
Discovery kit from overvoltage on VBUS. The USB Type-C® VBUS nominal voltage must be in the 5 V +/- 5%
range.
The following constraints apply to the USB Type-C® host types to be used:
•
•
Low-power USB hosts are not supported. Permanent damage might occur (100 mA is not sufficient to start
the Discovery kit).
USB 2.0 or USB 3.x legacy hosts might be used if they can provide 500 mA without data communication. In
practice, today nearly all of these ports deliver 500 mA without data communication. Prefer using USB
ports showing charging port marking in that case ( ), they enable higher current.
•
Any other USB Type-C® source type can supply and start up the STM32H7S78-DK board, up to 1.5 A.

User USB1
Figure 11 shows the 5 V DC power selection from user USB1 on JP1, with a power source connected to the
USB Type-C® connector (CN18).
User USB1 is a DRP port. A power switch with a TCPP03-M20 circuit is protecting the STM32H7S78-DK
Discovery kit from overvoltage on VBUS.
When USB1 provides 5V, the power selected on JP1[1-2] STLK or JP1[5-6] USB2 comes from the power input.
STLK can provide up to 3 A current and USB2 can provide up to 1.5 A current. The green LED (LD10) is lit when
the power source is selected. When USB1 accepts 5 V from other devices, JP1[7-8] must be closed as shown in
Figure 11.

6.4.6
MCU power supply - SMPS or LDO configurations
There are two possible solutions to provide power to the MCU VCORE logic supply: SMPS and LDO. Power
consumption in Run mode is significantly improved by generating VCORE from the internal DC-DC converter
(SMPS). The default power supply for VCORE logic must be SMPS. Some hardware modifications are required to
switch to LDO configurations. The hardware modifications are listed below:
•
SMPS mode (default):

microSD™ card
An SD 2.0 compliant slot (CN13) for microSD™ cards is available on the STM32H7S78-DK board and is
connected to the SDMMC1 interface of the STM32H7S7L8H6H. The uSD_Detect signal (PM14) manages the
microSD™ card detection. PM14 must be set as an open‑drain signal in STM32H7S7L8H6H. When a microSD™
card is inserted in the slot, the uSD_Detect signal level is LOW, otherwise, it is HIGH.
7.8
Audio
The STM32H7S78-DK features audio characteristics such as:
•
•
7.8.1
An audio codec with the I2S6 interface, a 3.5 mm audio jack connector for stereo earphones, and an
analog microphone,
A digital MEMS microphone and microphone daughterboard connector.
Audio codec
The audio codec is driven through an I2C1 interface (100 kHz). The I2C write‑read address is 0x34/0x35.
An I2S 5‑wire interface is transferring audio data. A dedicated PIO (Audio_INT, PM13) is used to receive interrupts
from this audio codec.
7.8.2
MEMS microphone
The digital MEMS microphone (U1) is soldered on the bottom side of the STM32H7S78-DK main board. A
microphone daughterboard connector (CN1) is implemented close to U1, to support the STEVAL-MIC008A
microphone daughterboard. Two microphones (left and right channels) can be used on this board. By default, U1
is connected to the data signal of SAI_PDM on the STM32H7S7L8H6H microcontroller. When a microphone
daughterboard is plugged into CN1, the data signal is switched to the microphone daughterboard automatically.
7.9
Virtual COM port
The serial interface UART4 (PD0/PD1) that supports the bootloader is directly available as a Virtual COM port of
the PC connected to the STLINK-V3EC USB connector (CN7). The VCP configuration is the following:

RF module
The STM32H7S78-DK Discovery kit includes one MB1400 Wi‑Fi® module, which is based upon a 802.11 b/g/ncompliant chipset.
Figure 14. MB1400 Wi‑Fi® module
The MB1400 Wi‑Fi® module is addressable over a UART or SPI interface. By default, the MB1400 uses the SPI
interface (SPI4) to communicate with the STM32H7S7L8H6H MCU.
The MB1400 Wi‑Fi® module does not require any operating system. It contains a complete and integrated TCP/IP
protocol stack that only requires AT commands to establish Wi‑Fi® network access and to enable STM32H7S78DK with Wi‑Fi® communication.
Note:
As the MB1400 Wi‑Fi® module firmware might evolve during the lifetime of the Wi‑Fi® module product, users
must make sure that the MB1400 Wi‑Fi® module firmware is up to date before starting to use the Wi‑Fi® module.

STM32H7S78-DK product information
10.1
Product marking
The stickers located on the top or bottom side of all PCBs provide product information:
•
First sticker: product order code and product identification, generally placed on the main board featuring
the target device.
Example:
Product order code
Product identification
•
Second sticker: board reference with revision and serial number, available on each PCB.
Example:
MBxxxx-Variant-yzz
syywwxxxxx
On the first sticker, the first line provides the product order code, and the second line the product identification.
On the second sticker, the first line has the following format: “MBxxxx-Variant-yzz”, where “MBxxxx” is the board
reference, “Variant” (optional) identifies the mounting variant when several exist, “y” is the PCB revision, and “zz”
is the assembly revision, for example B01. The second line shows the board serial number used for traceability.
Parts marked as “ES” or “E” are not yet qualified and therefore not approved for use in production. ST is not
responsible for any consequences resulting from such use. In no event will ST be liable for the customer using
any of these engineering samples in production. ST’s Quality department must be contacted prior to any decision
to use these engineering samples to run a qualification activity.
“ES” or “E” marking examples of location:
•
•
On the targeted STM32 that is soldered on the board (for an illustration of STM32 marking, refer to the
STM32 datasheet Package information paragraph at the www.st.com website).
Next to the evaluation tool ordering part number that is stuck, or silk-screen printed on the board.
Some boards feature a specific STM32 device version, which allows the operation of any bundled commercial
stack/library available. This STM32 device shows a “U” marking option at the end of the standard part number
and is not available for sales.
To use the same commercial stack in their applications, the developers might need to purchase a part number
specific to this stack/library. The price of those part numbers includes the stack/library royalties.
