I don't understand any of this. Could you please write precisely? Do you know the parameters of the C820 because I do not know what to look for in the store? The meter shows about 230 uF. I know it's not a precise measurement but it showed 1.5 times more than you wrote before. Which regulator can be blocked by the EN pin? Each? How can I find it? Most regulators only show 12V at the moment. I think she's resigning. Too many unknowns here.
