1.2 H407 or E407?

The major difference between STM32-H407 and STM32-E407 is that the latter has built-in Ethernet (physical level transceiver Micrel - Micrel datasheet). STM32-E407 also features an extra USB-OTG and a number of SMD jumpers on the bottom which help the user to control the multiplexing on some pins easier. STM32-E407 has 2 x USB-OTG both with a miniUSB interface. STM32-H407 has 1x USB-OTG and 1x USB-HOST with the On-The-Go interfaced by miniUSB and the HOST by USB type A connector.

If you need built-in Ethernet check the STM32-E407.

1.3 Target market and purpose of the board

STM32-H407 is a development board featuring a powerful ARM Cortex-M4F microcontroller with the most important peripherals, interfaces and connectors mounted and ready to use. The board can be powered by a number of different sources, can be programmed via two different interfaces, has a TON of GPIO pins available on a number of headers. The board's Arduino platform headers give another option for enthusiasts who wish to implement support for Arduino/Maple/Pinguino shields giving the board additional features altogether with the option to add Olimex extension modules on the OLIMEX UEXT.

All of the above options make the board quite versatile and suitable for numerous tasks and situations. The power of ARM and the creativity of OLIMEX come at the best price and the wellknown quality. Every ARM enthusiast would see STM32-H407 as an interesting bargain and quite capable board for its low price.

1.4 Organization

Each section in this document covers a separate topic, organized as follow:

– Chapter 1 is an overview of the board usage and features – Chapter 2 provides a guide for quickly setting up the board – Chapter 3 contains the general board diagram and layout – Chapter 4 describes the component that is the heart of the board: the STM32F207ZET6

microcontroller

– Chapter 5 is an explanation of the control circuitry associated with the microcontroller to

reset. Also shows the clocks on the board

CHAPTER 2 SETTING UP THE STM32-H407 BOARD

2. Introduction to the chapter

This section helps you set up the STM32-H407 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-H407 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-H407 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-H407, and that the programmer supports STM32F407 processor.

Additional components can be acquired in order to increase the functionality of the board:

- External power supply

- SD-card or USB-mini cable or extensive 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 SY0612E - power supply adapter 12V/0.5A for iMX233-STM32-H407

2.3 Powering the board

The board is powered in one of the following ways: 1) by PWR jack, 2) by JTAG/SWD

Page 7 of 28

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 (hibernate) during power down but it provides insufficient power for the board to operate properly. For example the RTC doesn't loose 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.

CHAPTER 3 STM32-H407 BOARD DESCRIPTION

3. Introduction to the chapter

In this chapter you will 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-H407 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 mode jumper table. The default positions of the tables are also shown.
