  • Great driver for LED-emitter Cree

    posted by evgenic on 16:14:56 G5T 06/05/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: A good universal buck-boost driver NANJG-28 for a different type and number of batteries 1 or 2 or 3 NiMn or 1Li . Uin Uout Iin Iout Pin Pout Effic % 1NiMH 1,30 3,10 1,03 0,23 1,34 0,71 53,25 2NiMH 2,60 3,30 1,08 0,61 2,81 2,01 71,69 3NiMH 3,95 3,43 1,16 0,92 4,58 3,16 68,87 1LiIon 3,92 3,44 1,16 0,90 4,55 3,10 68,09

    Cons: Many peoples complain about the failure of the output transistor. Necessary to provide additional cooling of the key elements (from the Throttle) so as not to damage it.

    Other: This driver may not be -ideal- for use with crappier Alkaline or NiMH/NiCad batteries, but with higher quality cells such as Eneloop NiMor Sanyo(Panasonic) Lithium. The use of a linear current regulator AMS7136 says about its capabilities. The quality of performance and its purpose - a worthy! I'm happy!

    Involvement Level: Expert (understands the inner workings)

    Pros: Works as stated!!
    Good regulation
    Quality workmanship
    Compact size for boost regulator

    Cons: heat issues as above?
    Not obvious where to put the negative battery wire - this must not go on the LED (-) as shown in one of the pictures above but on the outer rim conductor on the battery side. Is this why some units fail as above???

    Other: Good module does what it says in the title but make sure you choose the right module for the right job! If pure output is required over discharge cycle this is the one but if light levels are allowed to reduce resulting in longer useful light choose the other module..

    posted by rrobsonm on 01:40:07 G6T 20/06/2011 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: :- 5 modes - comes with lead wires (red, black) - HIGH, MED, LOW, STROBE, SOS modes - Clean and neat layout

    Cons: Q1 burned after a continous use of about 45min. After that, the boost-circuit doesnt work anymore. Current-regulation still works. You just CANT heatsink this thing properly. Q1 is not as high as the other components which makes it really hard... bad design... If the driver is meant to work without heatsink, then i got a faulty one. And the low mode is not really different from the mid (when using 3 nimh, on 2 it is better)

    Other: Good board nevertheless Get it!

    posted by heng84 on 22:44:20 G7T 25/07/2010 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Easy to use, ratings are accurate close to 1 amp when used with 18650 batt, not too hard to soldere, cheap and nice

    Cons: a little thick i prefer flat based one as certain flashlight only can be used, solder points a little to small for me but still i can fix it
    5 modes are kinda useless i prefer less modes

    Other: ok cheap nice easy to use, recommended i use it with q5 and r2 led quite good and bright. to have maximum output make sure u choose the correct set of batteries or else you will get low ma

    Involvement Level: Expert (understands the inner workings)

    Pros: First: I got the one from the picture. Works like promised. With memory.

    Cons: Q1 burned after a continous use of about 45min. After that, the boost-circuit doesnt work anymore. Current-regulation still works. You just CANT heatsink this thing properly. Q1 is not as high as the other components which makes it really hard... bad design... If the driver is meant to work without heatsink, then i got a faulty one. And the low mode is not really different from the mid (when using 3 nimh, on 2 it is better)

    Other: would be really nice, if there is no heat-problem

    posted by LobsterX on 01:22:20 G4T 06/04/2010 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: - 5 modes - comes with lead wires (red, black) - HIGH, MED, LOW, STROBE, SOS modes - Clean and neat layout

    Cons: I got a different 5mode board, the bottom had the following inscribed NANJG-112A Which happens to be a 4 group driver a plus if you know how to access those modes Taken off the net: Specifications: 1- Input voltage: 0.9~4.2V 2- Ouput current: 1.0A 3- Modes: 4-group memory modes 4- Diameter: 17mm with gold coated 5- In low mode, it turns to alarm when the voltage is about 2.75V. At this time, please stop working, in case it is damaged because of over discharge. Instructions: 1- AA battery: about 300~500mA max. 2- Brightness is controlled by single wafer, in case the over-current happens 3- New 4-group modes are completed by connecting with the five stars one after one. 4- Donot connect the wires reversely MCU brightness adjustment (DIY): 1- 2-mode: Low(10%)/High(100%) 2- 3-mode: Low(5%)/Mid(30%)/High(100%) 3- 3-mode: Low(5%)/High(100%)/Slow Strobe(2Hz, 2 times per second) 4- 5-mode: Low(5%)/Mid(30%)/High(100%)/Fast Strobe/SOS Note: 1- Face to the front, connect to the five stars clockwise one after one, then you will get 2 modes - 3 modes - 3 modes- 5 modes

    Other: Good board nevertheless Get it!

    posted by KentS on 04:43:46 G12T 05/12/2008 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Seems to pump out a lot of current on high, medium is still bright with a CREE R2 and for once low is really a low. Build quality seems good (I soldered on it and it still works :-))

    Cons: I don't care for SOS and strobe. Not a big con though. I don't know how well the regulation works, there is a lot of loss in intensity once the batteries start to drain (might be the fault of be the batteries though)

    Other: Good circuit board with a good selextion of modes and input voltages.

    posted by techjunkie on 17:04:33 G11T 21/11/2008 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Nice high mode, very bright, pulls 1.4A from 1 16340.
    Nice medium and low modes too. Low is very low about 50mA and medium is somewhere right in between.
    Has memory as advertised, returns to same mode you left it on (instead of next mode which would be really annoying).
    LED leads came pre-attached. Circuit boar looked well assembled.

    Cons: Modes occassionally don't switch on first try. Not sure why.
    SOS has long pause between each full SOS cycle. (Not what I'm used to seeing.)

    Other: Not too expensive and has the features advertised. I can't find a better driver board with modes and memory than this one here.

  • Quite good but warm up pretty quickly

    posted by nanotech17 on 06:32:51 G11T 21/11/2008 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Easy to hook up and looks neat too.The most easiest driver that i have across with compare to others.Diameter is just right not too wide.

    Cons: Quite good but warm up pretty quickly.So please ensure you use good heatsink to avoid overheating.

    Other: Recommended but please ensure attach it on a proper heatsink.Though i have to wait almost a month to get it but once arrived it's great.
