UM2407 Hardware layout and configuration
49
The Nucleo-144 board and its shield boards can be powered in three different ways from an
external power supply, depending on the voltage used. The three power sources are
summarized in
Table 6.
Figure 11. Power supply input from VIN (7 V to 12 V, 800 mA max)
Note: Refer to Section 6.4.6 about debugging when using an external power supply.
6.4.3 External power supply input 5V_EXT (5 V, 500 mA max)
When STM32H7 Nucleo-144 board is power supplied by EXT (Refer to Table 7 and
Figure 12), the jumper configuration must be the following: Jumper JP2 on pin 5-6 ‘EXT’
Note: Refer to Section 6.4.6 about debugging when using an external power supply.
