The board comes with incorrect capacitor values

Be careful with this version as it has no power on delay as the capacitor values actually differ from what is shown on the board. The result will be for the problem of the cotton, if it is turned on, this will not work. Replacing the 3 black caps in the middle of the board from 47,15,47 to the correct 100,50,100 introduces a 2 second delay and eliminates the power up process. The rest of the board works. Because I had the parts I didn't send them back, but many won't.
