In the uMite manual (page 24) the supply voltage for the TSOP4838 is 5v.

Reading the datasheet of the part (http://www.vishay.com/docs/82459/tsop48.pdf it states it can be used between 2.5v and 5v.

Is there a reason why the manual has 5v as i would prefer to use 3.3v.
Reliability, sensitivity?

Reading more.. the sensitivity should not make any difference according a graph on page 4.

Anyone experience with using it with 3.3v?

Jean,

I ran the parts on 10 units at 3.3 volts and they worked fine.
