Need help troubleshooting 8x8 array not fully lit

Hi everybody. I’m currently experimenting with the Rainbowduino. Today I connected it for the first time to my computer with a UartSB to program. It is powered, but I’m getting this with the default Rainbowduino CMD sketch uploaded to the board.

Below are some pictures about what I’m talking about.

And with a different 8x8 array.

I thought it had something to do with the Rext Pots, but turning them has no effect, I’m still getting the same pattern.

Any ideas?

That is normal with the power supply from the UartSB. It really needs an external 6.5V or greater supply to get the LEDs other than the red ones going.

Thanks. I’m going to be trying the power supply I ordered off the depot when it arrives.
