I know that the signal pin is regulated at 3.3 volts on the V4. I have a led array that I am powering from the signal and ground pin but 3.3 volts doesn't seem to be enough voltage.
Is there a way that I can power the LED's with more voltage and still be able to script light sequences?
I was looking at electronic PWM switches from servocity.com but they are ridiculously expensive in my opinion and figured there would have to be an easier way than to spend $30 for each port.
Thank you for your time

This topic comes up often and the transistor switch is about the easiest and most well known solution. The example pictures shows a common usages with a common micro controller like an Arduino, but the usages is the same with an EZb.
Take a look at that link and if you have follow up questions be sure to ask! Many of use have build similar circuits so if you get try it and have issues or questions don't be afraid to ask.

I mean, there are step up converters too...but, ehh.
I have another led array that doesn't need to be controlled on or off so i was able to turn up the voltage making the lights brighter.. However with the 3.3v regulator it is hard to achieve the same level of light.
LEDs usually have a high voltage maximum (~30V) and they are current driven (~20mA) so voltage doesn't matter too much as long as it's above the forward voltage (Vf) of the LED. I would probably suggest the same as the other forum members, use your input voltage controlled by a simple transistor like a 2N2222 (switching the ground connection to the LEDs ON and OFF) but make sure you use a high wattage resistor if you use a single resistor for current limiting. You can get away with lower wattage resistors if you use a resistor per LED.
You can then control the transistor with an ez-b digital pin and do PWM dimming to your heart's content
