Clock sources
The B-G474E-DPOW1 Discovery kit is using the internal HSI clock reference.
In case the user wants to apply external clock sources, there are three possible options:
•
X2, 24MHz oscillator footprint (not fitted by default)
•
MCO clock source coming from STLINK-V3E (not connected by default)
•
External clock source from extension connector (on PF0, pin 26 of CN9)
