RGB Driver/Wires Question
Franco B:
1) Yes you should be using the external ground because you should also be supplying the LED Wiz with 5v. This is because the LEDs you have connected could draw ~600-700mA on each LED Wiz and you only have ~500mA available from USB.
You need to feed the LED Wiz 5v and use the ground terminal to connect to the power source ground.
2) You don't need to utilise the bank select feature as you are just running 5v LEDs. However I bridged the +5v in and the banks like so:
I wasn't sure if this was correct so I PM'd randy and he said:

Could you take a look at this thread for me and tell me if I need to daisy chain the banks to the USB5v as I have in the 6th photo.

I don't think you needed them for what you are doing, but they won't hurt either. What you did was "proper though, and exactly how it should be done.

3) No the devices do not need to be linked. Its all handled by the software.

Ok, this is striking me as a bit off for some reason. You don't need to connect 5v to the LED-Wiz board anywhere but the "Bank Voltage Select" terminals. If the wire heading out of the photo is going to the PC power supply, it's not correct. That terminal is a tap into the 5v USB power, and shouldn't be tied to the PC supply.
But if that wire is going to your LEDs, that's fine, as long as the load is not greater than the 500ma spec of the USB port. This is what I thought was happening.
If you are going to the PC supply for the +5v, you don't want to hook anything to the "USB +5v" terminal at all.

Heh, I was just going off what you told me was correct, :P
Good job I haven't actually got round to using it yet :laugh:

You know I am a huge fan and consumer of your products...but any thoughts to updating the documentation for these products to include "LEDWIz for Dummies Pics or drawings"?
Would be nice since you always seem to be jumping into threads for corrections...I know I had a heck of a time figuring out what went where and it took a lot of searching in the forums and messages to others with the product. The docs you include are good just not great. Maybe a couple of pics showing a connection or even drawings showing a PSU etc would help a lot of new people to the product.
Just my 2 cents, again love the products just not a huge fan of the accompanying documentation! ;)
