The RGB Matrix Bonnet and RGB Matrix HAT make it easy to wire up the RGB Matrix and required power supply.
It is best to make all of these connections with the power unplugged, and then once everything is connected and you've double-checked that it's all correct, plug in the power to turn everything on. I've found that the Pi can complain about low power if its USB C power is not plugged in prior to the DC jack power on the Bonnet or Hat. So be sure to plug in the USB C power adapter first, then the adapters powering the Bonnet and any additional panels.

Pi 5 & Bonnet Connections
- Attach the Matrix Bonnet or Hat to the Raspberry Pi 5 GPIO pin rows.
- Connect theĀ USB C power cable to theĀ USB C jack to power the Pi.
- Connect the barrel jack of the DC 5V 4A power adapter into the barrel jack connector on the Matrix Bonnet or Hat.
- Connect the fork on the end ofĀ GND (black wire) lead on the matrix power cable to the - terminal block on the Matrix Bonnet or Hat.
- Connect the fork on the end of theĀ 5V (red wire) lead on the matrix power cable to the + terminal block on the Matrix Bonnet or Hat.
- Connect one end of a 2x8 IDC ribbon cable to the 2x8 pin connector on the Matrix Bonnet or Hat.
- Connect one end of the 4 pin matrix power cable connector to the 4 pin power input connector on the back of the matrix panel.
- Connect the other end of the 2x8 IDC ribbon cable to the inputĀ 2x8 pin connector on the back of the matrix panel. The input connector is the one that the arrows in the long direction point away from.
