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 is detailed. 2.1 Electrostatic warning STM32-E407 is shipped in a protective anti-static package. The board must not be exposed to high electrostatic potentials. A grounding strap or similar protective device should be worn when handling 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 to program/debug the board – to choose the correct programmer be sure that you are aware what software 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 not work 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 Page 7 of 32 OLIMEX© 2021 STM32-E407 user's manual 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 the power 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. Page 8 of 32 OLIMEX© 2021 STM32-E407 user's manual 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 were left 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. That way 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. 3.1 Layout (top view) 3.2 Layout (bottom view) On the bottom there are three tables printed – general jumper table, boot mode jumper table, power Page 9 of 32 OLIMEX© 2021 STM32-E407 user's manual mode jumper table. The default positions of the tables are also shown. Page 10 of 32 OLIMEX© 2021 STM32-E407 user's manual CHAPTER 4 THE STM32F407ZGT6 MICROCONTROLLER 4.

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.

We have tested a number of microSD cards on the STM32-E407 boards and all of them worked fine regardless manufacturer or capacity. However, keep in mind that some of the lower quality microSD cards might draw too much current from the slot which might cause power-state problems. If you suspect the microSD card is causing problems please try using another one of better quality for better results.

Those signals can be controlled by the provided jumpers. However, the jumpers are soldered by default 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. Their connection 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 jack has 2.0mm inner pin and 6.3mm hole. More information about the exact component might be found here: https://www.olimex.com/wiki/PWRJACK.

Page 19 of 32 OLIMEX© 2021 STM32-E407 user's manual 6.10 Battery connector When using the battery connector keep in mind that it is an energy solution that wouldn't be able to power 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. Pin # Signal name 1 VBAT 2 GND 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 output of 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. More information 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 the near 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. Page 20 of 32 OLIMEX© 2021 STM32-E407 user's manual 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 from three 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 is closed and B1_0 is closed the board will try to boot from System Memory. If B0_1 is closed and B1_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. Page 21 of 32 OLIMEX© 2021 STM32-E407 user's manual 6.12.7 GPIO port jumpers These are SMD type of jumpers located on the bottom of the board. They are located on the bottom of 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 Page 22 of 32 OLIMEX© 2021 STM32-E407 user's manual 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 it will download the compiler so it will take some time) 5) Select: Tools –> Board –> STM32-E407 6) Select: File –> Examples –> STM32-E407 –> 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.
