Hi,

I have foolishly fried C3 on my rainbowduino. Can’t see any other obvious damage so I would like to replace the capacitor to see if it still works. Can anyone give me the values for C3?

Cheers,

Scott.

Hi,

C3=47uF

#3

Thanks Icing,

I popped a 47uF electro on there & it seems to work with the RGB matrix now (-: Can’t get it to drive the cube though so I have some more investigating to do.

Cheers,

Scott.

I managed to do the same on one of my rainbowduinos.

As I have one of these capacitors available (http://www.earthshineelectronics.com/capacitors/59-electrolytic-capacitor-047f.html), I will try it and see if it works.
I am not an electronics person so can anywone tell me if this capacitor is not compatible or what would the implications be if I used it?

Is any of these two an identicall replacement?

For the information of anyone who has a similar problem, I replaced the tantalum (c3) capacitor with the electrolitic capacitor and the board is now functional.

I ll let you know if any problems occur in the future.
