    Pretty good circuit

    posted by maadcow on 05/15/2010 Certified Owner

    Involvement:General (knows how to use it) - Ownership:more than 1 month

    Pros:
    Worked like a charm! It fit perfectly into the project I had in mind for it. I used it with sku.03475 and sku.10084 for some very nice results running off of two AA batteries.
    Cons:
    The price. I also didn't really like the 5-mode circuit. It fell off. I don't really see the point in the other 4 modes anyway....

    weird modes

    posted by kapsel on 03/03/2010 Certified Owner

    Involvement:General (knows how to use it) - Ownership:1 week to 1 month

    Pros:
    gives enough mAh's for a step up converter quite cheap short mode memory- after about 3 seconds after turning off, it turns on again in first, HI mode, which is good in most cases
    Cons:
    really weird modes- the ones I recieved last time was HI->really LO->strobe->blink every 7 seconds. The previous batch I ordere...

    Great replacement circuit

    posted by xachopin on 06/04/2009 Certified Owner

    Involvement:General (knows how to use it) - Ownership:1 week to 1 month

    Pros:
    - It's 16mm, not 17mm as most driver in DX - As multiple modes - Easy to install - Works with 1 or 2 AA batteries - I haven't noticed any flickering at the low settings (but I only used it for a few seconds, so maybe if you stay on low longer you'll notice ...
    Cons:
    - No mode memory - The price could be a little lower. Other than that it's works great for the use I have. - I would have prefe...

    Cheap and decent boost driver for 2xAA

    posted by desolder on 12/25/2008 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:
    This is a cheap, decent boost driver for 2 NIxx/alkaline applications. It's a small size so it can fit in most spaces. It has 5 useful modes, not 20 crazy modes that nobody uses. If you want single mode, then it's easy to cut out the mode controller on top ...
    Cons:
    I wish efficiency was higher, but what can you expect for a dirt cheap boost converter?

    Not bad

    posted by Pelju on 07/08/2008 Certified Owner

    Involvement:General (knows how to use it) - Ownership:less than 1 day

    Pros:
    -As far as I know this is the only 16mm board here that can run a led with just 1x AA battery. -After reading those other reviews I was a bit afraid about the brightness this would offer with just 1.2 volt input to Q3 Cree.. but after I had prepared for the...
    Cons:
    -Low mode does flicker a little bit, but it's hardly noticeable so it doesn't bother me much.

    Jack of all trades

    posted by _Diceman on 06/04/2008 Certified Owner

    Involvement:General (knows how to use it) - Ownership:more than 1 month

    Pros:
    Comes pre-assembled. After dealing with unassembled drivers this is a big plus. Decent output and efficiency. Can be used as a single-mode driver by removing the microcontroller board. 16mm diameter.
    Cons:
    The microcontroller is the weak link in the chain, it's only benefit is to offer a (flickery) low mode. The strobe modes might ...
