Datasheet

Shut down your Pi and remove power. Plug the HAT or
Bonnet on so all the 2x20 pins go into the GPIO header.
Step 2. Connect Matrix Power cable to terminal block
Your RGB matrix came with a red & black power cable. One end has a 4-pin MOLEX connector that goes into the
matrix. The other end probably has a spade connector. If you didn't get a spade connector, you may have to cut off the
connector and tin the wires to plug them into the terminal block
