Hi,
I’m using the STM32MPU157x-DK2 development board and would like to power it externally, either using a battery or a different power source (not USB Type-C).
Could you please help with the following:
What are the recommended ways to provide external power, such as via a Li-ion/LiPo battery or regulated 5V supply?
Can I use the 5V input on the CN6 (EXP connector) to power the board?
Should I disconnect USB-C when supplying external power to avoid conflict?
Are there any voltage/current limitations, or specific battery protection requirements I should consider?
Do I need to change any configuration settings on the board to enable external power or battery supply?
