Review: NANJG 105A 2800mA driver

Flashlight Modding and DIY Parts
112

Nice call - It's gone now :).

I managed to pry the driver free from the host, and now everything works as it's supposed to. I have to get used to the memory mode, though.

113

Thanks, I was also in doubt for a while.

114

guys, I have lost the C1 on my 105C, probably got ripped away while modding lights:( does it affect something? do I need to replace it (if yes, with what capacity)?

115

It's just a buffer cap for suppressing noise on the MCU's voltage supply. These caps are usually in the 10nF - 100nF range. The driver will probably work without it, but you might see some random erratic behaviour.

116

Does anyone know the difference between NANJG 105A & NANJG 105C

It seems that 105A kept changing for a period.

The price difference is quite high, for 2 x 105C I can buy 3 x 105A , and I want to buy a 2-3 of these.

Is it possible to buy 105A and get the 105C ?

117

I don't think they make the 105A or 105B any more, I think it is 105C only now. I believe it is like a revision letter. I hope the 105D comes out soon I have been getting some bad 105Cs lately.

118

Now the links are working.

Then why the $2 in price difference? 105A appears available, check the first link.

What do you mean bad 105Cs, not working or, you have to clean the solder....?

119

Got some bad non working ones in my last order, mode issues.

Your links don't work.

Still not working ?

SKU: S009742 vs SKU: S004338

121

Nothing worse than a bad C to leave a lousy taste in your mouth.



;)

122

OK so far the difference between the two NANJG 105's :

SKU: S009742 $4.7 Product added on February 24 2011 http://kaidomain.com/ProductDetails.aspx?ProductId=10995#

SKU: S004338 $6.63 Product added on April 5 2011 http://kaidomain.com/ProductDetails.aspx?ProductId=1770

Which one have you guys bought? I asked if anyone knows the difference, but I guess that's going to be hard to answer to.


123

I have bought tons of the 105Cs. Take one for the team and order the other one so we all know what it is.

124

I've bought the $4.70 one several times. It is a good board with different mode groups available. The more expensive one (from the pictures) doesn't seem to have a microcontroller, so it *should* be a 1-mode 2.8A board (one of the reviews indicates it has modes, so either they are shipping something different or the review is for the wrong product). The second one may have a 2011 date, but the reviews go back to 2009.

125

Thanks guys!

126

I bought a few 5 packs (alot cheaper) and worked fine. I managed to kill one of the amc to get 350mA less draw for a comission speciality flashlight and the owner was happy for the added runtime and less heat and not much less output. At least not easily percieved drop in brightness.

127

You mean, a few 5 packs of the 105C, which are alot cheaper as the Kaidomain price? Do you have a link?

128

It's this product http://kaidomain.com/ProductDetails.aspx?ProductId=10995

just that here you buy 5 pcs

http://kaidomain.com/ProductDetails.aspx?ProductId=11088

If you buy 5 of the first link you pay $22.15 (that's the price for 5+)

But if you want to buy the 5 pcs pack you pay $21.79

129

I know the 5 Pack of Kaidomain, thank you.

But if he speaks about "alot cheaper" I think he doesn't mean save only $0,36 for 5 driver.

130

I think he refers to buying the one that costs $6.63 a piece. x5 = $33.15

So when you compare it that way it is a lot cheaper.

That's what I think since on CPF some users thought that only the $6.63 SKU is the only 8*AMC7135 driver.

We’re lucky here in Australia, anything under $1000 doesn’t attract any duty :slight_smile:
