Take a moment to review the components in the circuit diagram. This illustration is meant for referencing wired connections - the length of wire, position and size of components are not exact.
Note that in order to drive the 64x64 dot matrix display, you must connect GPIO pins 4 and 18.
RGB Matrix Bonnet connects to the Raspberry Pi Zero.
The 2.1mm Male DC adapter and will need to be 150mm long.
While it is okay to use a single power supply to feed both RPI and matrix display, it is important that the throughput is powerful enough.
5v 10A switching power supply is plenty for this project.
