I'm trying to power a matrix bonnet (https://www.adafruit.com/product/3211) with 5V Power Supply (https://www.adafruit.com/product/1466). The bonnet is not displaying a green light, indicating it is powered on. I checked the power supply voltage with a multimeter and it is working. I tried attaching to RGB matrix with molex connector and Raspberry Pi 4 (with separate power supply) and the bonnet did not power on. Any help would be appreciated!

I did notice the jack is slightly off-center when I received it but wasn't sure if this was normal

Re: RGB Matrix Bonnet Not Powering on
Let's check that power jack hardware a little more. Can you post another photo of the backside of the Bonnet. Like this view:

Re: RGB Matrix Bonnet Not Powering on
Thanks. That looks OK. Nothing obvious.
You mention measuring the power supply voltage. Was that directly on the power supply's barrel plug?
Are you also seeing no voltage if you measure the outputs at the terminal block? Can just probe the screws from the top:

Re: RGB Matrix Bonnet Not Powering on
I measured on the barrel, yes, it was disconnected from the bonnet. Then I measured the terminal block with the power supply connected and there was a very small voltage reading (.002 -.004).

Re: RGB Matrix Bonnet Not Powering on
OK, thanks for the check. Not sure what's wrong, but seems like something is up with the power. Let's just replace it.
Send an email to [email protected] with a link to this post and your order number and they can send you a replacement Bonnet.
