STM32 Nucleo-32 boards (MB1180)
Introduction
The STM32 Nucleo-32 boards based on the MB1180 reference board (NUCLEO-F031K6,
NUCLEO-F042K6, NUCLEO-F301K8, NUCLEO-F303K8, NUCLEO-L011K4, NUCLEO-
L031K6, NUCLEO-L412KB, NUCLEO-L432KC) provide an affordable and flexible way for
users to try out new concepts and build prototypes with STM32 microcontrollers, choosing
from the various combinations of performance, power consumption and features. The
Arduino™ Nano connectivity support makes it easy to expand the functionality of the
Nucleo-32 open development platform with a wide choice of specialized shields. The
STM32 Nucleo-32 boards do not require any separate probe as they integrate the ST-
LINK/V2-1 debugger/programmer and come with the STM32 comprehensive software HAL
library, together with various packaged software examples, as well as direct access to the

Page 10: Hardware Layout And Configuration
Hardware layout and configuration UM1956 Hardware layout and configuration The STM32 Nucleo-32 board is based on a 32-pin STM32 microcontroller in LQFP or UFQFPN package. Figure 2 illustrates the connections between the STM32 and its peripherals (ST-LINK/V2-1, push-button, LED, and Arduino Nano connectors). -

Page 16: Power Supply And Power Selection
VIN (7 V-12 V), +5 V (5 V) or +3V3 power supply pins on CN4. In case VIN, +5 V or +3V3 is used to power the STM32 Nucleo-32 board, this power source must comply with the standard EN-60950-1: 2006+A11/2009, and must be Safety Extra Low Voltage (SELV) with limited power capability. -
Page 17: External Power Supply Inputs
SB9 must be off. VIN or +5 V power supply When powered from VIN or +5 V, it is still possible to use ST-LINK for communication for programming or debugging only, but it is mandatory to power the board first, using VIN or +5 V, then to connect the USB cable to the PC. -
Page 18: 3V3 Power Supply
Using the +3V3 (CN4 pin 14) directly as power input, can be interesting, for instance, in case the 3.3 V is provided by a shield board. In this case the ST-LINK is not powered, thus programming and debugging features are not available. When the board is powered by +3V3 (CN4 pin 14), the solder bridge SB14 and SB9 (NRST) must be off. -
Page 19: Jp1 (Idd)
1. In applications where VCP is used for communication at a speed higher than 9600 bauds, it may be needed to use this solder bridge configuration, to use 8 MHz clock (MCO from ST-LINK) and get a more precise frequency. -
Page 20: Usart Virtual Communication
USART virtual communication Thanks to SB2 and SB3, the USART interface of STM32 available on PA2 (TX) and PA15 (RX), can be connected to ST-LINK/V2-1. When USART is not used it is possible to use PA2 as Arduino Nano A7. Refer to Table Table 7. -
Page 21: Arduino Nano Connectors
Arduino Nano connectors CN3 and CN4 are male connectors compatible with Arduino Nano standard. Most shields designed for Arduino Nano can fit the STM32 Nucleo-32 board. Caution: The I/Os of STM32 are 3.3 V compatible instead of 5 V for Arduino Nano. - Page 22 Hardware layout and configuration UM1956 Table 9.
