Page 10: Chapter 3 Setting Up The Stm32-H405 Board
3.1 Electrostatic warning STM32-H405 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 to avoid electrostatic discharge. -
Page 11: Software Requirements
It is a good idea to study the example that is provided by Olimex for your board. If you are not willing to purchase the software just use the evaluation version initially. Specifically, for STM32-H405 Olimex provides only IAR EW for ARM example. It is a good idea to download the latest time-limited evaluation version. -
Page 12: Powering The Board
Windows software and an USB cable. STM32-H405 has a built-in USB DFU bootloader that allows such programming. Programming STM32-H405 via the bootloader is a slow process that requires the re-configuration of SMD jumper. It is not recommend for initial evaluation, research and development (use any ARM JTAG debugger instead). -

3 and 4. 5.3 Power supply circuit The power supply circuit of STM32-H405 allows the board to be powered by three sources. The most used interface for powering is the USB type B connector. It works at 5V DC. The board can also be powered via the on-board JTAG connector. In that case the board receives 3.3V DC from the debugger tool. -
Page 17: Chapter 6 Connectors And Pinout
Notes regarding the interfaces are given. 6.1 USB connector The USB type B connector allows you to access the USB functionality of STM32-H405. This connector is can be used to power the board. The connector is sturdy and typically lasts much longer during extensive use compared to the USB mini or USB micro connectors. -
Page 18: Jtag/Swd Debug Connector
The on-board JTAG connector has 0.1” step of its pins. Below is the table with the signals of the JTAG. This interface can be used with the Olimex's OpenOCD debuggers. It is also compatible with most of the ARM debuggers available on the market. -
