STM32H755 C54/C58 For LDO Supply

bramble
Associate II

Hi,

According to mb1363 for the H755 Nucleo, in order to change from the default SMPS to internal LDO supply, to enable 480 MHz clock, I need to change C54/C58 from 100 nF to 2.2 uF. However it appears that there are no capacitors installed on my board (which is working fine BTW).

I'm guessing that the 100 nF's have been left off to make it easier to simply add the significantly larger capacitors needed with the LDO, and presumably getting away without the smaller ones? Have I missed something?

Also, just to confirm please that R33 is indeed 0 ohms, in other words it's another solder bridge.

Thanks in advance.
