Several verifications are needed before using the board for the first time to make sure that
nothing has been damaged during shipment and no components are unplugged and lost.
When the board is extracted from its plastic bag, please check that no component remains
in the bag. Main components to verify are:
1. The 25 MHz crystals (X1 and X4) may have been removed by a shock.
2. The camera connected on socket CN15 located on the right side of the board under the
JTAG connector may be unplugged. If this is the case, please refer to the note in
Section 2.18: Camera module to make sure to plug it in the correct position.
3. The microSD card may have been ejected from its connector CN6 (top left corner of the
board).
The plastic protection on the camera should be removed carefully as the connection is very
fragile.

2.1 Power supply
The STM3240G-EVAL evaluation board is designed to be powered by 5 V DC power supply
and to be protected by PolyZen from a wrong power plug-in event. It is possible to configure
the evaluation board to use any of following five sources for the power supply:
• 5 V DC power adapter connected to CN18, the power jack on the board
• 5 V DC power with 500 mA limitation from CN8, the USB-OTG FS Micro-AB connector
• 5 V DC power with 500 mA limitation from CN9, the USB-OTG HS Micro-AB connector
• 5 V DC power with 500 mA limitation from CN21, the ST-LINK/V2 USB connector
• 5 V DC power from both CN1 and CN3, the extension connector for daughterboard
(DTB for daughterboard on silkscreen)
The power supply is configured using jumpers JP4, JP32, JP18 and JP19 as described
in
Tabl e 2.

2.3 Clock source
Four clock sources are available on the STM3240G-EVAL evaluation board for
STM32F407IGH6 and RTC embedded:
• X1, 25 MHz crystal for Ethernet PHY with socket. It can be removed when clock is
provided by the MCU MCO pin
• X2, 26 MHz crystal for USB-OTG HS PHY
• X3, 32 kHz crystal for embedded RTC
• X4, 25 MHz crystal with socket for the,STM32F407IGH6 microcontroller (it can be
removed from socket when internal RC clock is used)
2.4 Reset source
The reset signal of the STM3240G-EVAL evaluation board is low active and the reset
sources include:
• Reset button B1
• Debugging tools from JTAG connector CN14 and trace connector CN13
• Daughterboard from CN3
• RS-232 connector CN916 for ISP
• ST-LINK/V2
2.5 Audio
The STM3240G-EVAL evaluation board enables stereo audio play and microphone
recording by an external headset connected on audio jack CN11. An audio DAC CS43L22 is
connected to both I2S2 port and a DAC channel and a microphone amplifier is connected to
the ADC of the STM32F407IGH6. CS43L22 can be configured via I2C1 and the external
PLL (U36) can be used to provide external clock which is connected to I2S_CKIN pin (PC9).
Note: To avoid speaker damage it is mandatory to connect the headphone to the board on CN11
during debug of audio code. When the program is stopped on a breakpoint, a DC voltage
may be applied to the speaker which induces power consumption incompatible with the
speaker.
Warning: Signal I2S_SD (PI3) is close to signal TCK/SWCLK of the
JTAG/SWD interface, so to avoid possible communication
issues on JTAG/SWD when the I2S interface is used the
recommendations are to:
1) Prefer usage of embedded ST-LINK/V2 to external tool
connected on CN14.
2) Configure PI3 GPIO in low speed (2 MHz or 10 MHz).

2.8 RS-232 and IrDA
Both RS-232 and IrDA communication are enabled by D-type, 9-pin RS-232 connectors
(CN16) and IrDA transceiver U11 which are connected to USART3 of the STM32F407IGH6
on the STM3240G-EVAL evaluation board.
The IrDA transceiver (TFDU6300) is not populated on STM3240G-EVAL evaluation board
from version C08. The version of the board is written on sticker on the bottom side of the
board (ex: MB786-C08). For boards version C08 or newer, it is possible to solder manually
the TDFU6300 on U11 footprint to support IrDA feature.
For ISP support, two signals are added on the RS-232 connector CN16:
• Bootloader_RESET (shared with CTS signal)
• Bootloader_BOOT0 (shared with DSR signal)
RS-232 or IrDA is selected via JP22. The position 2-3 of jumper JP22 is unused from
version C08 of the board. ISP is enabled via JP29 and JP34.
To enable the selected CAN transceiver to work in High-speed
mode, set JP7 as shown (default setting):

2.9 Motor control
The STM3240G-EVAL evaluation board enables a three-phase brushless motor control via
a 34- pin connector (CN5), which provides all required control and feedback signals to and
from the motor power-driving board. Available signals on this connector include emergency
stop, motor speed, 3-phase motor current, bus voltage, heatsink temperature coming from
the motor driving board and 6 channels of PWM control signal going to the motor driving
circuit.
The solder bridge (SB18) allows to choose two kinds of synchronization methods for PFCs
(Power Factor Correction) while the SB17 can be set for different signals on pin 31 of CN5.
The I/O pins used on motor control connector CN5 are multiplexed with some peripherals on
the board; either motor control connector or multiplexed peripherals can be enabled by the
setting of solder bridges SB10, SB11, SB12, SB14, SB15 and SB16.

2.12 ST MEMS
The ST MEMS device LIS302DL is connected to the STM32F407IGH6 I2C1 bus on the
board.
2.13 Potentiometer
A 10 kΩ potentiometer RV1 is connected to PF9 of STM32F407IGH6 on the board.
2.14 ADC
Two test points (TP3 AIN-) and (TP4 AIN+) are placed close to port PC1 of the MCU
allowing precise measurements on ADC1, ADC2 or ADC3 channel 11. As PC1 is also used
as current A input on the motor control connector it is recommended to remove R219 to
optimize noise immunity on this input.
A potentiometer RV1 is connected to PF9 of STM32F407IGH6. If needed, a low pass filter
(R74 and C59) can be placed on this input to reduce the bandwidth of the analog input PF9.
It is also possible to place the Ethernet PHY (U5) in low power mode in order to reduce the
noise induced by this high frequency peripheral. Power down pin (MII_INT in the schematic)
is connected to PB14 of the MCU, so this I/O can be configured as output low during analog
precision measurement.
2.15 USB-OTG FS
The STM3240G-EVAL evaluation board enables USB-OTG full speed communication via a
USB Micro-AB connector (CN8) and USB power switch (U1) connected to VBUS. The
evaluation board can be powered by this USB connection at 5V DC with a 500 mA current
limitation.
The LED LD6 indicates that the power switch (U1) is ON and STM3240G-EVAL functions as
a USB host or that the VBUS is powered by another USB host while STM3240G-EVAL
functions as a USB device. The LED LD5 indicates an over-current.
2.16 Ethernet
The STM3240G-EVAL evaluation board enables 10/100M Ethernet communication by a
PHY DP83848CVV (U5) and integrated RJ45 connector (CN7). Both MII and RMII interface

This oscillator (ref SM7745HEV-50.0M or equivalent) must be soldered on the U3 footprint
(located under CN3) and jumper JP5 must be removed. This oscillator is not provided with
the board.
2.17 USB-OTG HS
The STM3240G-EVAL evaluation board enables USB-OTG high speed communication via
a USB Micro-AB connector (CN9), USB high speed PHY (U8) and USB power switch (U4)
connected to VBUS. The evaluation board can be powered by this USB connector (CN9) at
5V DC with a 500 mA current limitation.
LED LD7 indicates that power switch (U4) is ON and the STM3240G-EVAL is working as a
USB host or that VBUS is powered by another USB host when the STM3240G-EVAL is
working as a USB device. The LD8 indicates an over-current. The USB ULPI bus is shared
with CAN2 bus, the JP10 and JP3 must be kept open for USB-OTG HS.
Jumper Description
JP31
To disable USB-OTG PHY U8, JP31 is not fitted.
Default setting: Fitted
Note: On boards MB786 prior to version B03 it is possible that after a board RESET the MCU is no
longer able to control communication with the OTG PHY (U8). When this issue occurs the
only way to recover OTG PHY control is to power the board OFF and ON. This issue is fixed
on MB786 version B03 or newer.

2.20 Development and debug support
Version 2 of the ST-LINK, called ST-LINK/V2, is embedded on the board. This tool allows
onboard program loading and debugging of the STM32F using the JTAG or SWD interface.
Third-party debug tools are also supported by the JTAG (CN14) or Trace (CN13)
connectors.
Note: Due to I/O sharing on the board there is a frequency limitation on ETM trace, so when the
MCU clock is above 120
To communicate with the embedded ST-LINK/V2, a specific driver needs to be installed on
your PC. To download and install this driver, refer to the software and development tools
page for the STM32F family available on www.st.com (the install shield is called
ST-LINK_V2_USBdriver.exe).
Third-party toolchains, Atollic TrueSTUDIO, KEIL ARM-MDK, IAR EWARM and Tasking VXToolset support ST-LINK/V2 according to the following table:

- RFU means Reserved for Future Use.
- As an option, RFU could be tied to VDD or VSS for forward
compatibility with future STM32F products. However, user may leave
RFU pin connected to VDD, or VSS, or NC for STM32F2xx exclusive
use.
- JP4 should be fitted for future backward compatibility
with sTM32F2xx.
