6.2 Embedded ST-LINK/V2 (or V2-B)
The ST-LINK/V2 on PCB version A or B or the ST-LINK/V2-B on PCB version C is
embedded as programming and debugging tool. Virtual COM port and USB mass storage
features are supported by the ST-LINK/V2-B only.
The embedded ST-LINK/V2 (or V2-B) supports only SWD for STM32 devices. For
information about debugging and programming features refer to ST-LINK/V2 in-circuit
debugger/programmer for STM8 and STM32, User manual (UM1075), which describes in
detail all the ST-LINK/V2 features.
The changes on ST-LINK/V2-B versus ST-LINK/V2 version are listed below. New features
supported on ST-LINK/V2-B are:
•Virtual Com port interface on USB
•Mass storage interface on USB
The embedded-on-board features not supported either on ST-LINK/V2 or on
ST-STLINK/V2-B are:
•SWIM interface
•Minimum supported application voltage limited to 3 V
•USB power management request for more than 100 mA power on USB
Known limitation:
activating the readout protection on the STM32 target, prevents the target application from
running afterwards. The readout protection must be kept disabled on the STM32 target.
There are two different ways to use the embedded ST-LINK/V2 (or V2-B), depending on the
jumper states (see Table 3):
•Programming/debugging the STM32 on board (refer to Section 6.2.4: Using ST-
LINK/V2 (or V2-B) to program/debug the STM32F303VCT6 on board)
•Programming/debugging the STM32 in an external application board, using a cable
connected to SWD connector CN2 (refer to Section 6.2.5: Using ST-LINK/V2 (or V2-B)
to program/debug an external STM32 application)
6.2.1 Drivers
The ST-LINK/V2 (or V2-B) requires a dedicated USB driver, which, for Windows® XP, 7, 8,
can be found at the www.st.com website. In case the STM32 Discovery is connected to the
PC before the driver is installed, some Discovery interfaces may be declared as "Unknown"
in the PC device manager. In this case the user must install the driver files, and from the
device manager he must update the driver of the connected device (see Figure 6).
Note: Prefer using the "USB Composite Device" handle for a full recovery.
Table 3. Jumper states
Jumper state Description
Both CN4 jumpers ON ST-LINK/V2 (or V2-B) functions enabled for on-board programming
(default)
Both CN4 jumpers OFF ST-LINK/V2 (or V2-B) functions enabled for application through external
CN3 connector (SWD supported)

Figure 6. USB composite device
6.2.2 ST-LINK/V2 (or V2-B) firmware upgrade
The ST-LINK/V2 (or V2-B) embeds a firmware upgrade mechanism for in-situ upgrade
through the USB port. As the firmware may evolve during the life time of the ST-LINK/V2 (or
V2-B) product (for example new functionalities, bug fixes, support for new microcontroller
families), it is recommended to visit the www.st.com website, before starting to use the
Discovery board and periodically, to stay up-to-date with the latest firmware version.
6.2.3 VCP configuration
The ST-LINK/V2-B on STM32F3DISCOVERY supports virtual Com port (VCP) on U2 pin 12
(ST-LINK_TX) and U2 pin 13 (ST-LINK_RX), which are connected to the STM32F303 MCU
target STM32 USART1 (PA9, PA10), thanks to SB11 and SB15 solder bridges.
The SB11 (PA9) and SB15 (PA10) default configurations for STM32F3DISCOVERY are
given in Table 5: Solder bridges.
6.2.4 Using ST-LINK/V2 (or V2-B) to program/debug the STM32F303VCT6
on board
To program the STM32F303VCT6 MCU on the board, simply plug in the two jumpers
marked in red on CN4, as shown in Figure 7: STM32F3DISCOVERY connections, but do
not use the CN3 connector as that could disturb the communication with the
STM32F303VCT6 of the STM32F3DISCOVERY.

6.2.5 Using ST-LINK/V2 (or V2-B) to program/debug an external STM32
application
It is very easy to use the ST-LINK/V2 (or V2-B) to program the STM32 on an external
application. Simply remove the two jumpers from CN4 as shown in Figure 8: ST-LINK/V2
connections, and connect the application to the CN3 debug connector according to Table 4.
Note: SB7 must be OFF if the CN3 pin 5 is used in an external application.

6.3 Power supply and power selection
The power supply is provided either by the host PC through the USB cable, or by an
external 5 V power supply.
The D1 and D2 diodes protect the 5 V and 3 V pins from external power supplies.
•5 V and 3 V can be used as output power supplies when another application board is
connected to pins P1 and P2. In this case, the 5 V and 3 V pins deliver a 5 V or 3 V
power supply and power consumption must be lower than 100 mA.
•5 V and 3 V can also be used as input power supplies, for example when the USB
connectors are not connected to the PC. In this case, the STM32F3DISCOVERY board
must be powered by a power supply unit or by auxiliary equipment complying with the
standard EN-60950-1: 2006+A11/2009, and must be Safety Extra Low Voltage (SELV)
with limited power capability.
Note: The board can be also powered through the USB USER connector and it is protected by D4
and D5 diodes when both USBs are connected (in which case, the 5 V power is around 4.4
volts).
6.4 LEDs
•LD1 PWR: red LED indicates that the board is powered.
•LD2 COM: LD2 default status is red. LD2 turns to green to indicate that
communications are in progress between the PC and the ST-LINK/V2.
•User LD3: red LED is a user LED connected to the I/O PE9 of the STM32F303VCT6.
•User LD4: blue LED is a user LED connected to the I/O PE8 of the STM32F303VCT6.
•User LD5: orange LED is a user LED connected to the I/O PE10 of the
STM32F303VCT6.
•User LD6: green LED is a user LED connected to the I/O PE15 of the
STM32F303VCT6.
•User LD7: green LED is a user LED connected to the I/O PE11 of the
STM32F303VCT6.
•User LD8: orange LED is a user LED connected to the I/O PE14 of the

6.6 USB device supported
The STM32F303VCT6 MCU is also used to drive the second USB Mini-B connector (USB
USER), which allows the board to be used as a USB Device. The STM32F3DISCOVERY
can then act as a USB joystick, mouse, or other similar device. If both USBs are connected,
diodes D4 and D5 protect the board and use the power from the USB ST-LINK.
The board can be powered through this USB USER connector, then LED1 PWR lights,
LED2 COM blinks and it can run an application in standalone mode.
6.7 ST MEMS E-compass (ST MEMS LSM303DLHC)
The LSM303DLHC is an ultra-compact low-power system-in-package featuring a 3D digital
linear acceleration sensor and a 3D digital magnetic sensor. It includes a sensing element
and an IC interface able to provide the measured acceleration to the external world through
an I2C serial interface.
The LSM303DLHC has dynamically user-selectable full scales of ±2g/±8g and is capable of
measuring acceleration, and a magnetic field full scale from ±1.3g to 8.1g with an output
data rate of 100 Hz or 400 Hz.
The STM32F303VCT6 MCU controls this motion sensor through the I2C interface.
6.8 ST MEMS Gyroscope (ST MEMS L3GD20)
The L3GD20 is an ultra-compact, low-power, three-axis-angular-rate sensor. It includes a
sensing element and an IC interface able to provide the measured angular rate to the
external world through the I2C/SPI serial interface.
The L3GD20 has dynamically user-selectable full scales of ±250 dps/±500 dps/±2000 dps
and is capable of measuring rates.
The STM32F303VCT6 MCU controls this motion sensor through the SPI interface.
6.9 JP3 (Idd)
Jumper JP3, labeled Idd, allows the measurement of the consumption of the
STM32F303VCT6 by removing the jumper and connecting an ammeter.
•Jumper on: STM32F303VCT6 is powered (default).
•Jumper off: an ammeter must be connected to measure the STM32F303VCT6 current.
If there is no ammeter, the STM32F303VCT6 is not powered.
