Before installing and using the product, please accept the Evaluation Product License Agreement from www.st.com/epla. For more information on the STM32 Nucleo boards and to access the demonstration software, visit www.st.com/stm32nucleo. 3.
UM1724 Quick start limitations to be worked around, as described hereunder. Parts with the date code starting from week 23 of 2015 contain bootloader V 9.2 in which the limitations no longer exist. To locate the visual date code information on the STM32L476RGT6 package, refer to its datasheet (DS10198) available on www.st.com, section Package Information. Date code related portion of the package marking takes Y WW format, where Y is the last digit of the year and WW is the week.
Features 4 UM1724 Features The STM32 Nucleo boards offer the following features: • STM32 microcontroller with LQFP64 package • Two types of extension resources – Arduino Uno Revision 3 connectivity – STMicroelectronics Morpho extension pin headers for full access to all STM32 I/Os • mbed-enabled(a) • On-board ST-LINK/V2-1 debugger/programmer with SWD connector – selection-mode switch to use the kit as a standalone ST-LINK/V2-1 • Flexible board power supply – USB VBUS – External VIN (7V
UM1724 Hardware layout and configuration The STM32 Nucleo board is designed around the STM32 microcontrollers in a 64-pin LQFP package. Figure 1 shows the connections between the STM32 and its peripherals (ST-LINK/V2-1, pushbutton, LED, Arduino connectors and STMicroelectronics Morpho connector). Figure 2 and Figure 3 show the location of these features on the STM32 Nucleo board. Figure 1. Hardware block diagram 67 /,1. SDUW 0LQL 86% (PEHGGHG 67 /,1.

Hardware layout and configuration 5.2 UM1724 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 5.2.3 UM1724 Using the ST-LINK/V2-1 to program/debug the STM32 on board To program the STM32 on the board, plug in the two jumpers on CN2, as shown in red in Figure 6. Do not use the CN4 connector as this could disturb the communication with the STM32 microcontroller of the STM32 Nucleo board. Figure 6.

Hardware layout and configuration UM1724 All parts of the STM32 Nucleo board and shield can be powered from the ST-LINK USB connector CN1 (U5V or VBUS). Note that only the ST-LINK part is power supplied before the USB enumeration as the host PC only provides 100 mA to the board at that time. During the USB enumeration, the STM32 Nucleo board requires 300 mA of current to the Host PC.

Hardware layout and configuration 16/61 UM1724 1. If more than 300 mA current is needed by the board, the PC may be damaged or the current supply can be limited by the PC. As a consequence the board is not powered correctly. 2. 300 mA is requested at enumeration (since JP1 must be OFF) so there is risk that the request is rejected and the enumeration does not succeed if the PC cannot provide such current. Consequently the board is not power supplied (LED LD3 remains OFF).
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.
Hardware layout and configuration 5.5 UM1724 Push buttons B1 USER: the user button is connected to the I/O PC13 (pin 2) of the STM32 microcontroller. B2 RESET: this push button is connected to NRST, and is used to RESET the STM32 microcontroller. Note: The blue and black plastic hats that are placed on the push buttons can be removed if necessary, for example when a shield or when an application board is plugged on top of NUCLEO.
UM1724 Hardware layout and configuration – • R35 and R37 removed HSE not used: PF0/PD0/PH1 and PF1/PD1/PH1 are used as GPIO instead of Clock The following configuration is needed: – SB54 and SB55 ON – SB16 and SB50 (MCO) OFF – R35 and R37 removed There are two possible default configurations of the HSE pins depending on the version of NUCLEO board hardware. The board version MB1136 C-01 or MB1136 C-02 is mentioned on sticker placed on bottom side of the PCB.
Hardware layout and configuration 5.7 UM1724 USART communication The USART2 interface available on PA2 and PA3 of the STM32 microcontroller can be connected to ST-LINK MCU, STMicroelectronics Morpho connector or to Arduino connector. The choice can be changed by setting the related solder bridges. By default the USART2 communication between the target MCU and ST-LINK MCU is enabled in order to support Virtual Com Port for mbed (SB13 and SB14 ON, SB62 and SB63 OFF).

Hardware layout and configuration 5.10 UM1724 Arduino connectors CN5, CN6, CN8 and CN9 are female connectors compatible with Arduino standard. Most shields designed for Arduino can fit to the STM32 Nucleo boards. The Arduino connectors on STM32 Nucleo board support the Arduino Uno Revision 3. For compatibility with Arduino Uno Revision 1, apply the following modifications: Caution: • SB46 and SB52 should be ON, • SB51 and SB56 should be OFF to connect I2C on A4 (pin 5) and A5 (pin 6 of CN8).
