Voltage output from the 21489 EZ-KIT LITE

Hi,

 

I'm developing an application on the ADSP 21489 EZ-KIT LITE, and I'd need to add some additional LED rings (considering these: http://mayhewlabs.com/products/rotary-encoder-led-ring) to my project. I wonder if I there's a location on the EZ-KIT board to draw the operating voltage (3.3V-5V, 3mA-45mA) for the LEDs, or would I have to use some other power source? I noted that the terminal TP23 gives the 3.3V, but this is probably not meant for this purpose... I'm sorry if it's a silly question, I'm rather new to embedded systems :-)

 

Thanks.
