BOARD USE REQUIREMENTS
Cables: The cable you will need depends on the programmer/debugger you use. If you use ARMJTAG, you will need LPT cable, if you use ARM-USB-OCD, ARM-USB-OCD-H, ARM-USBTINY, or ARM-USB-TINY-H you will need 1.8 meter USB A-B cable, for ARM-USB-OCD and
ARM-USB-OCD-H you will need RS232 cable, too.
Hardware: Programmer/Debugger – one of the Olimex ARM Programmers: ARM-JTAG, ARMJTAG-EW, ARM-USB-OCD, ARM-USB-OCD-H, ARM-USB-OCD-TINY, ARM-USB-OCD-H.
Note that Olimex OpenOCD debuggers lack SWD interface by default. There is the adapter ARMJTAG-SWD that adds SWD to any of the programmers/debuggers mentioned above.
Note the board can be programmed without a debugger using the serial port (the one with the
DE-9 connector).
Software: Any software that has support for ARM chips and more specifically for STM32F107.

JUMPER DESCRIPTION
STM32-P107 has a number of jumpers. They control the behavior of the board and allow modification of
the default hardware connections. There are two types of jumpers – PTH ones (big ones, easy to change
using a plastic cap) and SMT ones (pads that require cutting and soldering). It is safe to change the
position of the PTH jumpers as long as you use one of the legal positions of the jumper. Changing the
SMT jumpers, on the other hand, is not recommended – misconfiguration of the SMT jumpers might
damage the board.
There are jumper tables printed at the back of the board!
PTH jumpers:
B0_0/B0_1 and B1_0/B1_1 control the boot mode.
B0_0/B0_1
When this jumper is in position B0_1 – BOOT0 is connected to 3.3V, and when the
jumper is in position B0_0 – BOOT0 is connected to GND.
Default state is B0_0.
B1_0/B1_1
When this jumper is in position B1_1 – BOOT1 is connected to 3.3V, and when the
jumper is in position B1_0 – BOOT1 is connected to GND.
Default state is B1_0.
VBUS, USB_D+, and USB_D- are responsible for the USB host control. The host can be
routed to either the USB_OTG or the USB_HOST control.
VBUS
When is in position “H” - connects +5V_HOST_PWR to OTG_VBUS.
When is in position “O” - connects +5V_OTG_PWR to OTG_VBUS.
Default state is “O”.
USB_D+
When is in position “H” - connects USB_HOST_D+ to OTG_DP.
When is in position “O” - connects USB_OTG_D+ to OTG_DP.
Default state is “O”.
USB_DWhen is in position “H” - connects USD_HOST_D- to OTG_DM.
When is in position “O” - connects USB_OTG_D- to OTG_DM.
Default state is “O”.
RST_E and BOOT0_E jumpers are responsible for the system memory boot mode via UART
protocol.
Page 10 of 23
RST_E, BOOT0_E jumpers
Note that it is recommended to move those jumpers together – either both should be
open or both should be closed.
When both are closed RS232 boot is enabled (and also B0_0/B0_1 should be in B0/1
position). You can use Flash Load Demonstrator program provided for free by
STMicroelectronics: http://www.st.com/web/en/catalog/tools/PF257525
Default states are RST_E – open; BOOT_E – open.
SMT jumpers:
The SMT jumpers are typically used for hardware measurements and hardware debugging. Please do not
attempt to change the jumpers if you lack the soldering skills required.
3.3V_MCU_E
Enable microcontroller 3.3V power supply
Default state is closed.
3.3V_E
Enable regulator VR2 (3.3V) - LM1117
Default state is closed.
3.3VA_E

CONNECTOR DESCRIPTIONS
JTAG
The JTAG connector is used to program and debug the board via a third-party tool. It can be used for
JTAG and SWD programming and debugging. It is recommended to use with tools that have a compatible
20-pin 0.1 step connector.
The JTAG connector allows the software debugger
to talk via a JTAG (Joint Test Action Group) port
directly to the core. Instructions may be inserted
and executed by the core thus allowing
STM32F107 memory to be programmed with code
and executed step by step by the host software.
For more details please refer to IEEE Standard
1149.1 – 1990 Standard Test Access Port and
Boundary Scan Architecture and STM32F107's
datasheet and user's manual.

PWR_JACK
The board has a standard Olimex DC barrel jack with 2.0mm inner pin and 6.3mm hole. More
information about the exact component might be found here: https://www.olimex.com/wiki/PWRJACK
You can supply either DC or AC voltage to power the board however be careful – if you provide more
than the maximum voltage suggested, you would permanently damage the board.
The suggested voltage ranges for powering the board from the PWR_JACK are:
If you are powering the board from a DC power source – you need to provide between 6.5V and
9.0V of voltage.
If you are powering the board from an AC power source – you need to provide 6.0V of voltage.

The port can be used for DFU USB mode of the STM32F107 processor. To be able to upload data you
would need a mini USB cable connected to a personal computer that runs the proper software supplied by
Page 13 of 23
ST.
To enter the DFU mode you would also need to set the STM32-P107's jumpers properly. Make sure all
jumpers are set as per default and then change the jumper B0_0/B0_1 to position B0_1 – which means
boot from system memory.
More information about the DFU USB mode might be found at the ST's web-site. By the time of writing
this document more information and required files can be found at this link:
http://www.st.com/web/en/catalog/tools/PF257916
You can download the archive that contains the graphical user interface for DFU connection. It is called
“DfuSe Demo”. Extract it and install the software. Set the jumpers of STM32-P107 to boot from system
memory. Leave the rest of the jumpers as per default. Connect the STM32-P107 board to the computer
using a mini USB cable. This would show an unrecognized device in “Windows Device Manager”. Point
the driver updater to the folder where “DfuSe Demo” was installed. After the driver installation the board
would be recognized as “STM Device in DFU Mode”. At this point launch “DfuSe Demo” and restart the
board. A properly connected board looks like in the picture below:
For more information about DFU mode refer to the official USB and ST web-sites.
Page 14 of 23
RS232
The board can be programmed via the RS232 connector (serial interface). This is done without the need
of an additional programming tool. However, you would need a proper serial cable or adapter to access it.
You would also need to change the positions of three PTH jumpers (the rest of the jumpers should be as
per default):
1. B0_0/B0_1 should be set to position B0_1 – which means boot from system memory
2. RST_E should be closed
3. BOOT_E should be closed
Do not confuse B0_0/B0_1 with B1_0/B1_1.
After you set the jumpers and establish the hardware connection you need to download the software
provided by STMicroelectronics. It is called “Flash Loader Demonstrator”. It might be found here: http://
www.st.com/web/en/catalog/tools/PF257525 – after you install the software and establish connection you
can upload hex files to the board without the need of an expensive debugger. A properly recognized board
in “Flash Loader Demonstrater” is shown below:
Note that this method of programming is much slower than working with a debugger. Not only the upload
speed is low – you would need to perform hardware debugging routines to be able to track what is going
on.

If you hooked it to power, you affected it. To be clear, this includes items that have been soldered
to, or have had their firmware changed. Because of the nature of the products we deal with
(prototyping electronic tools) we cannot allow returns of items that have been programmed, powered
up, or otherwise changed post shipment from our warehouse.
All returned merchandise must be in its original mint and clean condition. Returns on damaged,
scratched, programmed, burnt, or otherwise 'played with' merchandise will not be accepted.
All returns must include all the factory accessories which come with the item. This includes any InCircuit-Serial-Programming cables, anti-static packing, boxes, etc.
With your return, enclose your PO#. Also include a brief letter of explanation of why the merchandise
is
being
returned
and
state
your
request
for
either
a
refund
or
an
exchange.
Include
the
authorization number on this letter, and on the outside of the shipping box.
Please note: It is your responsibility to ensure that returned goods reach us. Please use a reliable
form of shipping. If we do not receive your package we will not be held liable.
