IR Upgrade on Treo 680

November 26, 2008 Leave a comment

Exchanged two SMD resistors near IR module (the 33Ω and the 10Ω) for smaller values increasing current from 77mA to 150mA.

I’ve yet to perform conclusive tests to see if IR range has increased much, but the initial feeling is that it hasn’t.

There is scope to further increase the current, but until I’ve tested this first modifications effects I won’t know whether that would be worth it.
