I have 10 of these boards OctoBright CYANEA v2.0 connected in series, controlled by an Arduino.
Powering one or two off of the Arduino 5v pin has worked for testing. Now I want to scale it up to 10x boards. I been told that a computer power supply should be able to handle the load from all 10 of these boards in series.
Each board at max brightness consumes 500mA. 10 * 500mA = 5 Amps max
My questions are;
- Do I need to add any power conditioning to the output of the computers power supply?
- Can I directly connect the 5v rails from the computer's power supply to these boards?
- Anything I should know before I wire this up?
- Can I power the Arduino from the same 5v rail of the computers power supply?
