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.
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. This will avoid pressure on the buttons and consequently a possible permanent
target MCU RESET.

5.6 JP6
(IDD)
Jumper JP6, labeled IDD, is used to measure the STM32 microcontroller consumption by
removing the jumper and by connecting an ammeter.
removing the jumper and by connecting an ammeter.
Jumper ON: STM32 microcontroller is powered (default).
Jumper OFF: an ammeter must be connected to measure the STM32 microcontroller
current. If there is no ammeter, STM32 microcontroller is not powered.
