The RGB buttons we supply have connectors already attached and for other LEDs we sell packs of 10 pre-crimped wires. But maybe we need to re-think this and offer alternative options such as packs of crimp terminals. --- End quote --- I wouldn't worrry too much about it, this is BYOAC you know ;) I really liked the flexibility to make amy own harness just the way I wanted it (I like to tinker) I think most people would happy to use the harness you offer |

But I digress. Am I to understand that the anodes are intended to be driven off a pair of voltage pins controlled by the IC rather than straight off the positive rail? In other words, there's no way to sink more than 20mA worth of LEDs on each cathode? From the conversation here I'm confused as to where the limiter is occurring, on the anode or cathode side and whether I can remove that restriction by using 12v rail instead ??? --- End quote --- Each pin sinks 20ma. The current is fixed, regardless of the LED supply voltage. Thats the proper way to drive LEDs, with a constant current. Of course the voltage must be high enough to achieve the current. Using 12 volts would not increase the current. The only way to increase the current is to parallel multiple pins. |

Are there any plans for developing the "supplied application" farther? |
