Do I need to buy a separate battery pack or power supply to make this work?

Yes, This requires a separate power source and a little bit of wiring to an adapter. This is more a component for electronic builders than a "consumer-ready" product, by the way. You can use a 5V power supply (USB phone charger) easily - just hook it up using an adapter cable similar to this: https://www.amazon.com/CERRXIAN-Terminal-Solderless-Converter-Extension/dp/B07PDP1HCN/ref=sr_1_2?crid=1IX4U3BV3IRN1&dchild=1&keywords=usb+power+breakout+cable&qid=1606193600&sprefix=usb+power+break%2Ctools%2C157&sr=8-2 . This should work if you connect the red and black wires of the supplied controller to the positive and negative terminals of the USB cable. Otherwise, if you supply a different controller (like an Arduino Uno), you'll need to connect the power, ground, and data leads per the spec on the controller and program that controller.

Is a user manual available for the controller?

Yes. You can search SP002E. Then you can find the user manual.

What's the led breakdown per circle or where do i find that?
