Hello, I recently ordered an Led matrix 32x16 RGB for my Arduino Uno. Its pretty similar to the ones that adafruit sells. Since im a software engineer but pretty bad in electrical stuff, my question is: Is the power that my Arduino Uno provides enough to power the 5V 2A Led matrix over USB? If not, can i still use it? What would happen? In case i need an external power supply, can you recommend me one, and do i have to plug the external power supply into the arduino or directly into the 5V in
