Hi2all,
I'm afraid I know little about drivers. I do know that some manage to draw power form various batteries always delivering the same amount of current to the LD and others seem to vary wildly based on the input voltage (such as my DX Dilda & O-Like 532nm module).
My recent O-Like 532nm 120-150mW module tends to vary greatly depending on wether I use a 3.0V (4.3V fully charged) or 3.6V (5.4V) CR123A. The former puts out 96mW while the latter 130mW... . The module should be able to put out 120~150mW using a 3.0V battery, afaik... :thinking:
This may or may not be ok, but I noted a couple of resistors were bridged by solder and wanted to ask if this is ok (they may be used serial for the same path, I don't know...).
Attached, an image of a prior module's driver and the current module's driver with the bridged resistors.
Please let me know if you think this could have a bearing on the output, thanks!
