ST STM32 Nucleo-64-P User Manual

Hardware layout and configuration UM2206
26/55 UM2206 Rev 3
9.8 Reset sources
The reset signal of the STM32 Nucleo-64-P board is active low and the reset sources include:
• Reset button B2
• Embedded ST-LINK/V2-1
• Arduino Uno V3 connector from CN8 pin 3
• ST morpho connector CN5 pin 14
9.9 Virtual COM port: LPUART1/USART1
The LPUART1 or USART1 interface of the STM32 can be connected to:
• The ST-LINK/V2-1 MCU
• The Arduino Uno V3 connectors: CN9 (pins 1 and 2)
• The ST morpho connector (pins 35 and 37).
The LPUART1 or USART1 interface is selected by setting the related solder bridge (see
Table 9 and Table 10).
By default:
• Communication between target STM32 and ST-LINK/V2-1 MCU is enabled on
LPUART1 to support the virtual COM port
• Communication between target STM32 and Arduino and ST morpho connector is
enabled on USART1
The virtual COM port settings are configured as: 115200 b/s, 8 bits data, no parity, 1 stop bit,
no flow control.
9.10 LEDs
Four LEDs are available on the STM32 Nucleo-64-P board. The four LEDs are located on
the top side of the board.
