CHAPTER 2 SETTING UP THE STM32-E407 BOARD
2. Introduction to the chapter
This section helps you set up the STM32-E407 development board for the first time.
Please consider first the electrostatic warning to avoid damaging the board, then discover the
hardware and software required to operate the board.
The procedure to power up the board is given, and a description of the default board behavior isdetailed.

2.1 Electrostatic warning
STM32-E407 is shipped in a protective anti-static package. The board must not be exposed to highelectrostatic potentials. A grounding strap or similar protective device should be worn whenhandling the board. Avoid touching the component pins or any other metallic element.

2.2 Requirements
In order to set up the STM32-E407 optimally, the following items are required:- JTAG or SWD interface programmer/debugger* – can power the board and gives the ability toprogram/debug the board – to choose the correct programmer be sure that you are aware whatsoftware tools you are going to use when programming STM32-E407, and that the programmer
supports STM32F407 processor.
*The board can also be programmed with Arduino IDE via USB cable with mini USB connector
using board's USB-OTG1 connector;
Additional components can be acquired in order to increase the functionality of the board:- External power supply- USB type “A” to USB type “mini” cable is required for bootlader- SD-card or extension UEXT modules are recommended but not required- 3.7V Battery- MOD-XXXX boards for additional features on the UEXT (RTC, TC, GSM, MP3, RS-485 among
others) – note that you will have to implement the software setup between the boards- Arduino/Maple/Pinguino shields – every shield is hardware compatible with H407 but will notwork out-of-the-box, software implementation should be considered
Some of the suggested items can be purchased by Olimex, for instance:
ARM-USB-TINY-H – high-speed OpenOCD ARM JTAG debugger
ARM-USB-OCD-H – high-speed OpenOCD ARM JTAG debugger with buffer protection
USB-MINI-CABLE – USB mini to USB-A cable
BATTERY-LIPO1400MAH – lithium-polymer battery 1400mAh

USB-SERIAL-CABLE-F – easy way to connect the board to a computer terminal program using
the BOOT pins
SY0612E – power supply adapter 12V/0.5A for iMX233-STM32-E407

2.3 Powering the board
The board is powered in one of the following ways: 1) by PWR jack, 2)by JTAG/SWD programmer(3)by USB-OTG.
The PWR jack should be supplied from a 6V to 16V source with maximum current of 1A from thepower jack. Without additional components and peripherals (no microSD card mounted, nothing
connected to the USB, etc.) the typical consumption is 30mA @ 12V. For the European customers
we sell an affordable power supply adapter 12V/0.5A – SY0612E.
It is worth mentioning that the board can NOT be powered by the battery connector. The battery
connected keeps some of the processor's functions remain intact during power down but it provides
insufficient power for the board to operate properly. For example the RTC doesn't lose the values
when there is a battery connected.

2.4 Prebuilt software
Upon powering initially the board's red PWR LED and the green PWR LED should turn on. There
are demo examples available for download at the product's page at the Olimex's web-site.

CHAPTER 3 STM32-E407 BOARD DESCRIPTION
3. Introduction to the chapter
Here you get acquainted with the main parts of the board. Note the names used on the board differ
from the names used to describe them. For the actual names check the STM32-E407 board itself.
The board comes with a bag with 4 headers for the Arduino/Maple/Pinguino platform which wereleft unsoldered in case you don't wish to use those environments or you don't plan on using shields.
There is also a bag of 4 rubber pads which can be placed in the 4 corner holes of the board. Thatway the board will be safe from short-circuiting on the bottom if placed on low-resistance surface.
The placement stability of the board will also increase.

CHAPTER 5 CONTROL CIRCUITY AND HARDWARE
MODULES5. Introduction to the chapter
Here you can find information about reset circuit and quartz crystals locations, the power supply
circuit is discussed.

5.1 Reset
STM32-E407's reset circuit includes R5 (10KΩ), R6 (1 KΩ), C19 (100nF) and a RESET button.

5.2 Clocks
There are two quartz crystals available on the board:
12 MHz quartz crystal Q1 is connected to pins 23 and 24 of the CORTEX-M4F processor.
Quartz crystal Q2 is a 32 768Hz RTC (real-time clock) and is connected to pins 8 and 9. The GND
pin of the RTC quartz crystal is not soldered to allow easier change.

5.3 Power supply circuit
The power supply circuit of STM32-E407 allows flexible input supply from 6V to 16V direct
current. This means a wide range of power supplies, adapters, converters are applicable. The
maximum amperage the board can draw is 1A.
Note that the Li-Po battery connector cannot be used to fully power the board. Its function is to
give an option to save internal data if the board needs to be relocated. It will keep the RTC alive,
for instance.
If you have successfully powered the board the red PWR LED will turn on. Note that it is possible
to have the PWR LED on even if there isn't enough power for proper operation of the board and all
the peripherals currently connected.

6.4 USB_OTG1
USB On-The-Go, often abbreviated USB OTG, is a specification that allows USB devices such as
digital audio players or mobile phones to act as a host allowing a USB flash drive, mouse, or
keyboard to be attached and also connecting USB peripherals directly for communication purposes
among them.
Note DFU bootloader uses the USB_OTG1 port, and a "USB micro-A" cable is required. This is theport used to program the board via Arduino IDE.
Note that the USB-OTG ESD protection ICs are not placed by default. However, there are pads
provided for such protection.

6.7 Arduino/Maple platform
The Arduino/Maple platform connectors (2x6 pin and 2x8 pin plastic headers) are not mounted but
are included in the package. The reasons for not mounting the headers on the pin holes are two: first
you might not need them if you do not wish to experiment with Arduino/Maple software; second
there are two rows depending on the shield you might want to use the difference between the tworows is the distance between the two digital rows one is made according to the Arduino shieldstandard (e.g. you want to mount the row there if using Arduino certified shield), the other one isadjusted properly at 100mil step (e.g. you want to solder the digital pins here if using properly
adjusted shields).
The pinhole names are printed near the actual pinhole on the top of the board.

6.8 20-pin connectors – PD – PE – PF – PG
The 4 20-pin connectors combine different processor ports and provide very nice GPIO option –you can use them with your breadboarding wires, you can mount headers, you can take measures,etc, etc.
Note that all 4 headers come without connectors (unlike the UEXT or the JTAG) and connectors
are not included in the package (unlike the Arduino platform). However they follow the standard
100mil step connectors – not hard to find and mount/solder if needed etc.

Note that all signals marked with asterisk (*) are multiplexed with signals of the Arduino platform.
Those signals can be controlled by the provided jumpers. However, the jumpers are soldered bydefault which enables them on the GPIO connector and the Arduino shield at the same time.
PG11, PG13, PG14, PG16 and PG17 are multiplexed with the UEXT and the Ethernet. Theirconnection is not controlled by jumpers.

6.9 PWR Jack
The power jack used is the typical one used by Olimex in most of our products – the DC barrel jackhas 2.0mm inner pin and 6.3mm hole. More information about the exact component might be foundhere: https://www.olimex.com/wiki/PWRJACK.

6.10 Battery connector
When using the battery connector keep in mind that it is an energy solution that wouldn't be able topower the board and all the peripherals!
It help keeping information in the processor if you need to transport the board from one power
supply to other.

The pin names are also written on the bottom of the board in the base of the connector.

6.11 BOOT pads
The best use for the GND, RX3, TX3 pins from the BOOT connector would be getting the outputof the available demo program on a computer terminal via USB-SERIAL-CABLE-M(https://www.olimex.com/Products/Components/Cables/USB-Serial-Cable/USB-Serial-Cable-M/)
BOOT are 3 pinholes set on USART3 and are named on the bottom – GND, RX3, TX3 and notice
there are two vias near them which are actually VCC and can be used if connecting BOOT. Moreinformation about booting over UART can be found in the processor's datasheet.

6.12 Jumper description
Please note some of the jumpers on the board are SMD type. If you feel insecure in your soldering/
cutting technique it is better not to try adjusting SMD jumpers.
Also if you feel incapable of removing the PTH jumper with hand better use tweezers. We do.
6.12.1 PWR_SEL
PWR_SEL is important PTH jumper allowing easy switching of input current. You can use tweezers
to reach it. If you are powering the board via the PWR_JACK set it to position 1-2 (default → to thenear edge of the board).
If powering from the JTAG/SWD set the jumper in position 3-4.
If powering from the USB-OTG2 set it in 5-6 position (near battery connector).
If powering from the USB-OTG1 set it in 7-8 position (near LAN connector).
The default position is 1-2.

6.12.2 B1_1/B1_0 and B0_1/B0_0
These two PTH jumpers set where the board should boot from. B1_1/B1_0 and B0_1/B0_0 are
PTH jumpers and their position can be changed relatively easy. The board can try to boot fromthree places and that depends on the position of the B1_1/B1_0 and B0_1/B0_0 – User Flash
Memory, System Memory or the Embedded SRAM.
Notice that these two jumpers must be moved together – they are responsible for the boot mode if
bootloader is present.
The DFU bootloader is found on USB_OTG1.
If B0_0 is closed the board will try to boot from User Flash Memory.
If B0_1 is closed there are two variants depending on the state of B1_1/B1_0 jumper – if B0_1 isclosed and B1_0 is closed the board will try to boot from System Memory. If B0_1 is closed andB1_1 is closed bootloader must be located in the Embedded SRAM.
The default positions are B0_0 and B1_0 (Boot from User Flash Memory).
6.12.3 R-T
This is SMD type jumper.
If you close/solder this jumper RST and TRST at the JTAG will be connected.
The default position is open/unsoldered.
6.12.4 3.3V_E
This is SMD type jumper.
Board digital power will be disabled if open/unsoldered
The default position is closed.
6.12.5 AGND_E
This is SMD type jumper.
If open/unsoldered will disable analog ground.
The default position is closed.
6.12.6 AREF_EN
This is SMD type jumper. If open/unsoldered will disable ADC reference.
The default position is closed.

6.12.7 GPIO port jumpers
These are SMD type of jumpers located on the bottom of the board. They are located on the bottomof the board. We provided those in case you want to separate the multiplexing between the Arduino
shield and the GPIO connectors. Check chapter 6.8 for more information on the multiplexing.
Generally if you wish to avoid the multiplexing you have to cut the wire between the pads.

6.13 Additional hardware components
The components below are mounted on STM32-E407 but are not discussed above. They are listed
here for completeness:
Reset button – used for hardware reset of the board
WKUP button – can be used as user button
User LED + Power LED

CHAPTER 7 HOW TO USE THE BOARD WITH ARDUINO IDE
In order to program the board with Arduino IDE you would need a USB cable with mini USB
connector. Note that you you would also need to enter bootloader mode by manipulating the B0_1/
B0_0 and B1_1/B1_0 jumpers.
1) Download and install latest Arduino IDE.
2) Go to: File –> Preferences –> Additional Boards Manager URLs:
https://raw.githubusercontent.com/OLIMEX/Arduino_configurations/master/STM/
package_olimex_stm_index.json
3) Tools –> Board –> Boards manager…
4) Select "Olimex STM32 boards" –> Install (if Arduino SAM Boards package is not installed itwill download the compiler so it will take some time)5) Select: Tools –> Board –> STM32-E407
6) Select: File –> Examples –> STM32-E407 –> <choose one of the examples>7) Connect the USB cable to USB_OTG1 port of STM32-E407.
8) Set the board in DFU bootloader mode (set jumper B0_1/B0_0 –> B0_1; and B1_1/B1_0 –>B1_0 and reset the board)
8.1) If the device is not recognized install driver (WinUSB) using Zadig installer(download link: http://zadig.akeo.ie/)
9) Compile and upload the sketch
10) Run the board in the default boot from flash mode (jumpers B0_1/B0_0 –> B0_0; B1_1/B1_0–> B1_0 and reset the board)11) The uploaded sketch would be executed.
You need to set the jumpers in DFU bootloader mode every time that you want to upload. Then to
execute the code, revert the jumpers back to boot from flash mode and reset.
