STM32 Nucleo boards

Introduction

The STM32 Nucleo board (NUCLEO-F030R8, NUCLEO-F072RB, NUCLEO-F103RB,

NUCLEO-F302R8, NUCLEO-F401RE, NUCLEO-L152RE) provides an affordable and

flexible way for users to try out new ideas and build prototypes with any STM32

microcontroller lines, choosing from the various combinations of performance, power

consumption and features. The Arduino™ connectivity support and ST Morpho headers

make it easy to expand the functionality of the Nucleo open development platform with a

wide choice of specialized shields. The STM32 Nucleo board does not require any separate

probe as it integrates the ST-LINK/V2-1 debugger/programmer. The STM32 Nucleo board

comes with the STM32 comprehensive software HAL library together with various packaged

software examples, as well as direct access to mbed online resources at mbed.org.

UM1724 5.2 Hardware layout and configuration Embedded ST-LINK/V2-1 The ST-LINK/V2-1 programming and debugging tool is integrated in the STM32 Nucleo boards. The ST-LINK/V2-1 makes the STM32 Nucleo boards mbed enabled. The embedded ST-LINK/V2-1 supports only SWD for STM32 devices. For information about debugging and programming features refer to UM1075 - ST-LINK/V2 in-circuit debugger/programmer for STM8 and STM32, User manual, which describes in detail all the ST-LINK/V2 features.

Hardware layout and configuration 5.2.1 UM1724 Drivers The ST-LINK/V2-1 requires a dedicated USB driver, which can be found on www.st.com for Windows Vista, 7 and 8. On Windows XP the ST-LINK/V2-1 driver requires WinUsb to be installed before using the ST-LINK/2-1 (either available from Microsoft website or included in the USB driver for ST-LINK/V2 for XP).

UM1724 Hardware layout and configuration turned OFF. In such case it is mandatory to use an external power supply as explained in the next chapter. When the board is power supplied by USB (U5V) a jumper must be connected between pin 1 and pin 2 of JP5 as shown in Table 7. JP1 is configured according to the maximum current consumption of the board when powered by USB (U5V).

UM1724 5.3.3 Hardware layout and configuration External power supply input: + 3V3 It can be of interest to use the +3V3 (CN6 pin 4 or CN7 pin 12 and pin 16) directly as power input for instance in case the 3.3 V is provided by an extension board. When NUCLEO is power supplied by +3V3, the ST-LINK is not powered thus the programming and debug features are unavailable. The external power sources +3.3V is summarized in the Table 8. Table 8. +3.
