Help with red module! :)

Hey all

Just found a aixiz module with a red diode and rdkstr driver, how do I check what ma it's set to and what batteries should I power it with?

Just to clarify, by module you mean that the diode attached to the driver, correct?

You can always compare to ur other builds..

First off,

Look at the driver, does it have a pot or no?
If it doesn't have a pot, what are the resistors labeled as?

IIRC the voltage drop on rkcstr drivers is 2.25v
Your going to need at least 7.25V to power it, and the rkcstr driver has a maximum voltage in of 12v.

Okay I think it's set to 390ma just checking old pms about the order. I'll check if it has a pot when I get home.. Just want to build a labby with it.. What's the highest ma I can safely run an lpc-815 at? With good heatsinking..

 

[Mohrenberg]

we use to run them at 400-420mA normally, but even at that it will die eventually......

 

[tommii89]

Sweet, thoughts on best battery configuration? Also, any good cheap host put there for red builds?

 

[Mohrenberg]

any 2x lithiums should work fine. at long as your in the 7.25-12v range.

Appreciate it man! I'll make it this week

How do you find a voltage drop in a laser?
