Drivers
Before connecting STM32F412ZGT6 to a Windows^® XP, 7 or 8 PC via USB, a driver for
ST-LINK/V2-1 must be installed. It can be downloaded from the www.st.com website.
In case the 32F412GDISCOVERY discovery kit is connected to the PC before the driver is
installed, some 32F412GDISCOVERY interfaces may be declared as "unknown" in the PC
device manager. To recover from this situation the user must install the driver files, and
update the driver of the connected device from the device manager (see Figure 7).
Prefer using the "USB Composite Device" handle for a full recovery.

ST-LINK/V2-1 firmware upgrade
ST-LINK/V2-1 employs a dedicated MCU with Flash memory. Its firmware determines
ST-LINK/V2-1 functionality and performance. The firmware may evolve during the life span
of the 32F412GDISCOVERY to include new functionalities, fix bugs or support new target
microcontroller families. It is therefore recommended to keep the
ST-LINK/V2-1 firmware up to date. The latest version is available from the www.st.com
website.
Power supply
Power supply sources
The 32F412GDISCOVERY discovery kit is designed to be powered by the following
sources:
• 5 V DC from the ST-LINK/V2-1 USB connector CN6 with 500 mA current limitation.
Power mechanism of supplying the discovery kit by the ST-LINK/V2-1 is explained in
Section 6.3.4: Supplying the 32F412GDISCOVERY through the ST-LINK/V2-1 USB
port. A jumper should be placed in location STLK of JP3, connecting pins 3 and 4. The
green LED LD6 is lighted on to confirm the presence of +5 V voltage.
• 5 V DC from the user USB FS connector CN3. A jumper should be placed in location
USB of JP3, connecting pins 5 and 6. The green LED LD6 is lighted on to confirm the
presence of +5 V voltage.
• 6 V to 9 V DC from VIN pin of Arduino Uno V3 compatible connector CN2. The voltage
is limited to 9 V to keep the temperature of the regulator U3 within his thermal safe
