STLINK-V3MODS and STLINK-V3MINI debugger/programmer
tiny probes for STM32 microcontrollers
Introduction
STLINK-V3MODS and STLINK-V3MINI are stand-alone debugging and programming tiny
probes for STM32 microcontrollers. These products are designed in a very low form factor
and both offer high performance without any compromise to functions. They support the
JTAG/SWD interfaces for communication with any STM32 microcontroller located on an
application board.
They provide a Virtual COM port interface allowing the host PC to communicate with the
target microcontroller through one UART. The STLINK-V3MODS also provides bridge
interfaces to several communication protocols allowing for instance the programming of the
target through the bootloader.
The STLINK-V3MODS and STLINK-V3MINI are both proposed for different uses. The
STLINK-V3MODS may be directly soldered on a host PCB including an STM32 application-
based with its 2 x 16-pin castellated vias connection, while the STLINK-V3MINI offers
STDC14 connectivity with an included STDC14 to STDC14 flat cable.

description
5.1 STLINK-V3MODS and STLINK-V3MINI overview
STLINK-V3MODS and STLINK-V3MINI are stand-alone debugging and programming tiny
probes for STM32 microcontrollers. These products support many functions and protocols
for debugging, programming, or communicating with one or several targets.
These modules are fully powered by the PC. If the COM LED blinks red, refer to the
technical note Overview of ST-LINK derivatives (TN1235) for details.
5.2 STLINK-V3MODS and STLINK-V3MINI frequency selection
The STLINK-V3MODS and STLINK-V3MINI run internally at three different frequencies:
•high-performance frequency
•standard frequency, compromising between performance and consumption
•low-consumption frequency
By default, the STLINK-V3MODS and STLINK-V3MINI start in high-performance frequency.
It is the responsibility of the toolchain provider to propose or not the frequency selection at
the user level.
5.3 High-performance modules
The STLINK-V3MODS and STLINK-V3MINI support high-performance configuration for
STM32 microcontrollers. The working voltage range is from 3.0 to 3.6 V.
The protocols and functions supported are:
•SWD (up to 24 MHz) with SWO (up to 16 MHz)
•JTAG (up to 21 MHz)
•VCP (from 732 bps to 16 Mbps)

5.5 STLINK-V3MODS and STLINK-V3MINI functions
All functions are designed for high performance: all signals are 3.3 V compatible. The
following description concerns STLINK-V3MODS and STLINK-V3MINI except for some
mentioned sections and indicates where to find the functions on the boards and connectors.
5.5.1 SWD with SWV
SWD protocol is a Debug/Program protocol used for STM32 microcontrollers with SWV as a
trace. The signals are 3.3 V compatible and may perform up to 24 MHz. This function is
available on CN2 (STLINK-V3MODS) and CN5 (STLINK-V3MINI).
5.5.2 JTAG
JTAG protocol is a Debug/Program protocol used for STM32 microcontrollers. The signals
are 3.3 V compatible and may perform up to 21 MHz. This function is available on CN2
(STLINK-V3MODS) and CN5 (STLINK-V3MINI).
5.5.3 Virtual COM port (VCP)
The serial interface VCP is directly available as a Virtual COM port of the PC, connected to
STLINK-V3MODS and STLINK-V3MINI USB connector CN5. This function may be used for
STM32 microcontrollers. The signals are 3.3 V compatible and may perform from 732 bps to
16 Mbps. This function is available on CN2 (STLINK-V3MODS) and CN5 (STLINK-V3MINI).
A second Virtual COM port may be activated on STLINK-V3MODS, as detailed later in
Section 5.5.5 (Bridge UART).
For details regarding baud rates, refer to section 14.2. of the user manual STLINK-V3SET
debugger/programmer for STM8 and STM32 (UM2448).
5.5.4 Mass storage interface
The STLINK-V3MODS and STLINK-V3MINI tiny probes implement a virtual mass storage
interface allowing the programming of an STM32 target Flash memory with drag-and-drop
action of a binary file from a file explorer. This ability requires the STLINK-V3MODS or
STLINK-V3MINI tiny probe to identify the connected target before enumerating it on the
USB host. As a consequence, this functionality is available only if the target is connected to
the STLINK-V3MODS or STLINK-V3MINI tiny probe when it powers up.
The mass storage interface may be disabled or enabled again by reprogramming the
ST-LINK firmware. This can be performed with the STLinkUpgrade application. Activate the
<change type> checkbox then select the firmware with or without mass storage and launch
the update. The action is reversible.
5.5.5 Bridge functions (STLINK-V3MODS only)
The STLINK-V3MODS tiny probe provides a proprietary USB interface allowing the
communication with an STM32 target with several protocols: SPI, I2C, CAN, UART and
GPIOs. This interface may be used to communicate with the target bootloader, but may also
be used for customized needs through its public software interface. All bridge signals are
accessible on CN2.

STLINK-V3MODS and STLINK-V3MINI functional description UM2502
16/28 UM2502 Rev 2
Bridge SPI
SPI signals are available on CN2 pins 7, 14, 23, and 25.
Bridge I2C
I2C signals are available on CN2 pins 16 and 17. It is necessary to add externally 680 Ω
pull-up resistors on the host application board.
Bridge CAN
CAN logic signals (Rx/Tx) are available on CN2 pins 9 and 10, they may be used as input
for an external CAN transceiver.
Bridge UART
UART signals with hardware flow control (CTS/RTS) are available on MB1467 CN2 pins 1,
2, 3, and 11. They need dedicated firmware to be programmed on the main module before
being used. Without this firmware, the Virtual COM port function must be used instead (no
hardware flow control).
Bridge GPIOs
Four GPIO signals are available on CN2 pins 18 and 21. Basic management is provided by
the public ST bridge software interface.
5.5.6 LEDs
Power LED: Red light indicates that 5 V is enabled.
COM LED: Refer to the technical note Overview of ST-LINK derivatives (TN1235) for
details.
Fault LED: Indicates USB overcurrent request.

1. RX signals are inputs for STLINK-V3MODS, outputs for the target.
2. SWO is optional, required only for Serial Wire Viewer (SWV) trace.
3. TX signals are outputs for STLINK-V3MODS, inputs for the target.
4. Can drive 5 V +/- 5% with a 200 mA maximum current.
5. NC means not required for SWD connection.
6. Input for STLINK-V3MODS.
5 V source output capability
Pin 22 of the right edge pin connector can drive a 5 V target with a maximum output current
of 200 mA. The 5 V is guaranteed to be in the +/- 5% range if the driven current does not
exceed 200 mA. Please notice that exceeding this maximum output current over 200 mA
may damage the device or cause communication issues with the host PC (A PC standard

6.1.3 STDC14 for STLINK-V3MINI (STM32 JTAG/SWD and VCP)
The CN5 STDC14 connector allows the connection to an STM32 target using the JTAG or
SWD protocol, respecting (from pin 3 to pin 12) the ARM10 pinout (Arm Cortex Debug
connector). But it also advantageously provides two UART signals for the Virtual COM port.
The related pinout for the STDC14 connector is listed inTable 4.

7 Product information
7.1 Product marking
The stickers located on the top or bottom side of the PCB provide product information:
•Product order code and product identification for the first sticker
•Board reference with revision, and serial number for the second sticker
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.
Evaluation tools marked as “ES” or “E” are not yet qualified and therefore not ready to be
used as reference design or in production. Any consequences deriving from such usage will
not be at ST charge. In no event, ST will be liable for any customer usage of these
engineering sample tools as reference designs or in production.
“E” or “ES” 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.
