ESP32-U4WDH and VDD_SDIO power

Postby cdunkel » Wed Nov 16, 2022 6:30 am

Hi,
I got a question which seems not clearly answered in the HW documentation.

ESP32-U4WDH which has internal flash, does VDD_SDIO power needs to be connected at all?
If so, shall it be connected to 100nF or 100nF and VCC which is 3v3?

Thanks for your inputs

You'd need to connect it to an 100nF capacitor.
