Hi, I am testing my New 32x32 RGB LED Matrix panel with the colourwheel32x32 code provided in Arduino examples library.
When the panel is not connected with the external power supply it shows erroneous result which is not a colorwheel as shown in Adafruit website but it shows the same colorwheel when we plugin external power supply. I am using a printed board over Arduino Mega to make connections and have checked the continuity check which is found out to be ok. I have a spare LED panel aswell but with that also, results are same.
Later, I used a direct connection between Arduino and Panle using jumper wires but still the issue is not rectified.
Please help in this regard. I have attached some links to images which would help you better understand the situation.

Re: Adafruit 32x32 RGB LED Matrix problem
It may have something to do with you custom board. There's a ready to go shield available here:

Also note that direct connection with jumper wires is not guaranteed, see warning box at top of page here:
