If you reduce the brightness of the matrix, powering everything via USB should be sufficient for testing. However, it is recommended to use a high-quality power supply for normal operation. A 20W (5V/4A) power supply is sufficient for this.


The 1000uF capacitor prevents the initial onrush of current from damaging the pixels. It also provides a small power reservoir for abrupt changes in brightness that the power source might not otherwise handle. Otherwise it can happen that the microcontroller restarts or it comes to gliches in the matrix.
