New Matrix Portalkit not displaying patterns correctly

Post by Uaweee »

Hello Adafruit Team,

I ordered the LED matrix M4 kit with order number 3077215-5479591000 a few days ago.

Contents:
1 x Adjustable Bent-Wire Stand - up to 7" Tablets and Small Screens[ID:1679]
= $4.95
1 x Mini Magnet Feet for RGB LED Matrices (Pack of 4)[ID:4631] = $2.50
1 x Adafruit Matrix Portal Starter Kit - ADABOX 016 Essentials[ID:4812] =
$69.95

I connected everything according to the online manual but the lighting patterns I load for the LED seem rather random instead of what they are supposed to show. Even the official preinstalled glitter that turns with the LED is not working.

The USB-cable does not seem to be the issue since everything else is working normally, and using Circuit Python to access the M4 also worked. Any steps how to troubleshoot/fix this or do I just have a faulty M4?

Kind regards
Marv

It is probably related to the USB cable / power.

Is the cable USB-C on both sides?

Do you know if the USB-C cable is a USB 3.x PD ?

Is the port the USB-C cable is plugged into a USB 3.x PD port?
