Capacitors on Vdd SPI

Postby sandstorm412 » Tue Mar 14, 2023 6:52 pm

I'm making a custom board that uses the S2FH4 so it has flash and i don't need external psram.

my question is, do I need the capacitors on Vdd SPI?

Thank you

Yes. It's still a power rail for the internal flash, so you still need those caps.
