GDuP @ 350mA?

I would like to mod one of my GDuP boards to output 350mA on high, as opposed to the stock setting of 700mA. What value resistor would I need to alter this? I see a 0.10 Ohm current sense resistor on the board... Would I need to change this to a 0.20 Ohm, or is there another resistor involved?

Thanks!
 
Sounds about right based on what I have seen on SS regarding boards & resistors for setting levels. If there is another place for a second resistor, you might be able to add a second 0.1.

But don't take my word for it. I am used to DD everything!
 
.2 sounds about right assuming the sense resistor is for high. Measure the voltage across the sense resistor & see if you get around .07v?

so you need to replace the 0.10 with a 0.20?
Not add 0.10 on the free place?
I want to do this as well, so I can get a 350mAh max.
