Embedded ST-LINK/V2
The ST-LINK/V2 programming and debugging tool is integrated on the STM32F411
Discovery board. The embedded ST-LINK/V2 can be used in 2 different ways according to
the jumper states (see Table 2):
Program/debug the MCU on board,
Program/debug an MCU in an external application board using a cable connected to
SWD connector CN2.
The embedded ST-LINK/V2 supports only SWD for STM32 devices. For information about
debugging and programming features, refer to user manual UM1075 (ST-LINK/V2 in-circuit
debugger/programmer for STM8 and STM32) which describes in detail all the ST-LINK/V2
features.

Using ST-LINK/V2 to program/debug the STM32F411 on board
To program the STM32F411 on board, simply plug in the two jumpers on CN3, as shown in
Figure 6 in red, but do not use the CN2 connector as that could disturb communication with
the STM32F411VET6 of the STM32F411 Discovery board.

Using ST-LINK/V2 to program/debug an external STM32 application
It is very easy to use the ST-LINK/V2 to program the STM32 on an external application.
Simply remove the 2 jumpers from CN3 as shown in Figure 7, and connect your application
to the CN2 debug connector according to Table 3.
Note:
SB13 must be OFF if you use CN2 pin 5 in your external application.

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:
4.3
4.4
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 the power
consumption must be lower than 100 mA.
5 V can also be used as input power supplies, e.g. when the USB connector is not
connected to the PC.
In this case, the STM32F411 Discovery board must be powered by a power supply unit
or by an auxiliary equipment complying with standard EN-60950-1: 2006+A11/2009,
and must be Safety Extra Low Voltage (SELV) with limited power capability.
LEDs
LD1 COM:
LD1 default status is red. LD1 turns to green to indicate that communications are in
progress between the PC and the ST-LINK/V2.
LD2 PWR:

the STM32F411VET6.
USB LD8:
The red LED indicates an overcurrent from VBUS of CN5 and is connected to the I/O
PD5 of the STM32F411VET6.
Pushbuttons
B1 USER:
User and Wake-Up button connected to the I/O PA0 of the STM32F411VET6.

On board audio capability
The STM32F411 uses an audio DAC (CS43L22) to output sounds through the audio mini
jack connector.
The STM32F411 controls the audio DAC through the I2C interface and processes digital
signals through an I2S connection or analog input signal.
4.6
The sound can come independently from different inputs:
–
ST MEMS microphone (MP45DT02): digital using PDM protocol or analog when
using the low pass filter.
–
USB connector: from external mass storage such as a USB key, USB HDD, and
so on.
–
Internal memory of the STM32F411.
The sound can be output in different ways through audio DAC:
–
Using the I2S protocol
–
Using the microphone output directly via a low pass filter to analog input AIN4x of
the CS43L22
USB OTG supported
The STM32F411 is used to drive only USB OTG full speed on this board. The USB microAB connector (CN5) allows the user to connect a host or device component, such as a USB
key, mouse, and so on.
Two LEDs are dedicated to this module:
4.7
LD7 (green LED) indicates when VBUS is active
LD8 (red LED) indicates an overcurrent from a connected device.
E-compass MEMS (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 the acceleration, and a magnetic field full scale from ±1.3 g to 8.1 g with an
output data rate of 100 Hz or 400 Hz.
The STM32F411VET6 MCU controls this motion sensor through the I2C interface.
4.8
Gyroscope MEMS (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.

4.9
JP2 (Idd)
Jumper JP2, labeled Idd, allows the consumption of STM32F411VET6 to be measured by
removing the jumper and connecting an ammeter.
Jumper on: STM32F411VET6 is powered (default).
Jumper off: an ammeter must be connected to measure the STM32F411VET6 current,
(if there is no ammeter, the STM32F411VET6 is not powered).

BOOT0 configuration
BOOT0 is at level “0” through a pull-down R28. If you want to set BOOT0 at level “1”, it can
be configured by setting a jumper between P2.21 (BOOT0) and P2.22 (VDD).
Note:
If you need to set BOOT0 at level "1" continuously, then open SB19 solder bridge to avoid a
consumption of 6 mA, while connecting pin P2.21 and P2.22 with a jumper or with a wire.

Extension connectors
The male headers P1 and P2 can connect the STM32F411 Discovery board to a standard
prototyping/wrapping board. STM32F411VET6 GPI/Os are available on these connectors.
P1 and P2 can also be probed by an oscilloscope, logical analyzer or voltmeter.
