Topic: Could there be a 7660 laying around? (Read 90 times) previous topic - next topic

I had a Mega that went belly up so I decided to get a Due ... not realizing my shields wouldn't work without some modifications 'due' to the 3.3v requirement of the new Arduino...

So I was reading a thread about the 16x2 LCD display and someone commented:

Insert a 7660 voltage pump as U3 and 10uF Tantalums as C1 and C2, open J1. that's it.
I see on the circuit board of the display itself exactly where those things go, but I'm wondering...

Could there be something electronic that I might have laying around that would have a 7660 in it? 

Like what kinds of devices might I find one of these in?  Id rather salvage than make a new purchase if I can.

See attached pic to see how easy this would be...

Thank you,

Mike
