445nm amc7135 problems with building
- Thread starter mpmsfilho
- Start date
Are you using actual 7135 ICs, or a driver from somewhere, like deal extreme based on 7135? Here is a link to data sheet with typical application.
If you are using flashlight driver, positive connection is normally made right in the center, it is just a through hole to your power source, negative pad may be in several places. You can ohm it out with DMM if you like for a pad that is parallel with the output pins of the 7135s. Or, if you give me a sku # for the driver I can attempt to point it out to you.

Lucky bugger.... DX say they are waiting on stock for mine 
Does it look like the picture by The GMan here?

If so, that is pretty obvious.
Otherwise, if it is like the green boards in the product photo, the positive is in the center and the negative pad is also clearly marked to the right of center.
On the back side of course, your battery positive is the center and the battery negative is the outer ring.

My stock of sku 1885 actually looks more like the product photo, but is on a blue PCB and has 2 diodes for polarity protection. On the back, it is marked NANJG 10 but they all work pretty much the same way. I have had mine for a long time though.
Let me know if that is clear enough for you. If not, you can take a photo of yours and we will make sure you know what to do.

But...But... it says in stock ships in 2 to 4 days? You aren't saying DX would lie would you? Hah. I just cancelled my order today for sku 4382.Lucky bugger.... DX say they are waiting on stock for mine
Says in stock ships in 4 to 7 days. I have been waiting for over 5 months.
If I can help you find another source or anything, let me know. Or if you need just one asap we could work something out.

They should know better than to piss off the volcano 
I have dealt with DX before and it is just what everyone has come to expect. I sent in a support request, usually they will ship it asap if they get a request to cancel ^_^
It would still be nice to slap someone in the DX shipping department though.
I'm accustomed to being able to give a cuff upside the head to the one that has cost me my valuable time in person lol.
