STM3240G-EVAL evaluation board
Introduction
The STM3240G-EVAL evaluation board is a complete demonstration and development
platform for the STM32 F-4 series and includes an embedded STM32F407IGH6 high-
performance ARM®Cortex™-M4 32-bit microcontroller.
The full range of hardware features on the board is provided to help you evaluate all
peripherals (USB OTG HS, USB OTG FS, ethernet, motor control, CAN, MicroSD card,
smartcard, USART, Audio DAC, RS-232, IrDA, SRAM, MEMS, EEPROM… etc.) and
develop your own applications. Extension headers make it possible to easily connect a
daughter board or wrapping board for your specific application.
The in-circuit ST-LINK/V2 tool can be easily used for JTAG and SWD interface debugging
and programming.

1.4 Delivery recommendations
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 25MHz 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 replug 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
STM3240G-EVAL evaluation board is designed to be powered by 5V 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:
●5V DC power adapter connected to CN18, the Power Jack on the board
●5V DC power with 500 mA limitation from CN8, the USB OTG FS Micro-AB connector
●5V DC power with 500 mA limitation from CN9, the USB OTG HS Micro-AB connector
●5V DC power with 500 mA limitation from CN21, the ST-LINK/V2 USB connector
●5V DC power from both CN1 and CN3, the extension connector for daughterboard
(DTB for daughterboard on silkscreen)
The power supply is configured by setting the related jumpers JP4, JP32, JP18 and JP19 as
described inTable 1.
Table 1. Power related jumpers and solder bridges
Jumper Description
JP4 JP4 should be fitted to enable power down reset (PDR). PDR is disabled when JP4 is not fitted.
Default setting: Fitted.
JP32
MCU_VDD is connected to 3.3V power when JP32 is closed and MCU current
consumption measurement can be done manually by multi-meter when JP32 is
open.
Default setting: Fitted.
JP18
JP18 is used to select one of the five possible power supply sources.
To select the ST-LINK/V2 USB connector (CN21) power
supply, set JP18 as shown:
(Default setting)
