trailervert Posted December 24, 2013 Share Posted December 24, 2013 Hi Guys, I finally got around to installing my track ball leds. I am using Ultimarc's "U-Trak RGB LED Illumination Kit". I have it controlled with a Pac64Led. It works fine but the board gets SUPER hot in just a matter of minutes. It got hot enough that you could feel it through the ball, which is how I noticed it and then unhooked it. Anyone else experiencing anything like this? The power and ground are both coming from the Pac64 board. Link to comment Share on other sites More sharing options...
trailervert Posted December 24, 2013 Author Share Posted December 24, 2013 Found it, Pac64 is 12v and U-Trak RGB LED Illumination Kit is 5v. Link to comment Share on other sites More sharing options...
Polemicist Posted December 25, 2013 Share Posted December 25, 2013 LOL. Was gonna ask that. there isn't enough circuitry on that board for it to heat up unless it was in an over current state. Link to comment Share on other sites More sharing options...
connorsdad Posted December 25, 2013 Share Posted December 25, 2013 I have mine wired to my pacled64 and it works just fine. This is how it tells you to set it up on the ultimarc site. Sent from my SM-N9005 using Tapatalk Link to comment Share on other sites More sharing options...
Polemicist Posted December 25, 2013 Share Posted December 25, 2013 I was wondering about that. I thought the PACLed was USB powered and therefore 5V unfortunately my cab is still in planning phase so all I my info is just theory. How did you find you had 12V going into your trackball and where was it getting that current from? Link to comment Share on other sites More sharing options...
connorsdad Posted December 25, 2013 Share Posted December 25, 2013 The pacled64 is powered via a spare molex connector. I have this connected to the 5v (red) power line. Is the 5v power line not giving you the brightness you want ? Sent from my SM-N9005 using Tapatalk Link to comment Share on other sites More sharing options...

connorsdad Posted December 25, 2013 Share Posted December 25, 2013 " Connecting Power and USB The PacLED64 is supplied with a power cable which plugs onto a spare PC power supply hard drive power connector. When shipped, the + (positive) wire is not inserted into the connector housing. There is a choice of 5 volt or 12 volt power available on HDD power connectors. Select as follows: If you are using mainly LEDs with in-built resistors: Select the location which mates with the YELLOW wire on the PC connector. This is 12 volts. Examples of this type of LED are: * Ultimarc Ultralux pushbutton LEDs * Ultimarc U-Trak trackball illumination kit * All 5 volt or 9 volt LED lamps If you are using mainly LEDs without resistors (standard LEDs): Select the location which mates with the RED wire (5 Volts). Using 5 volts reduces power wastage and keeps the temperature of the driver ICs on the board to acceptable levels. Also, connect the USB cable to a USB port on the PC."
