Ken,

 

I should have made clear that 555 and NE555 can be used inter-changeably.  They are the same part.  I looked at your module listing and saw the comment about 35mA output capability.  It's puzzling.  The module uses the 555 chip and from what I can tell there is nothing on the module that limits the 555 from operating at its full current driving capability which is over 100mA.  Well, it appears to use a small LED that might be tied to the output but this should not consume that much of the available current.

 

Not that you would know or think to look, but one reason the 555 IC is still used by the billions even today is because of its high output current capability.  100mA is high current for a chip like this.
