Figure 12. Power supply input from VIN (from 7 V to 12 V, 800 mA maximum)
External power supply input from E5V (5 V, 500 mA maximum)
When the STM32WL Nucleo-64 board is power-supplied by E5V (refer to Table 7 and Figure 13), the jumper
configuration must be the following: JP4 [5-6] jumper E5V.
Table 7. External power sources: E5V (5 V)
Input power name
Connector pins Voltage range Maximum current
E5V CN7 pin 6 4.75 V to 5.25 V 500 mA
Refer to Section 6.4.1 for debugging when using an external power supply.
