Hello all,
I recently posted about an issue im having with the Sunfounder LED matrix caused by a change on the production side that was out of my control. I make and sell a product that is an all-in-one stream deck/LED fag box housing/mount and with my sun founder issues, I did a redesign to make it work with the 8x8 WS2812B LEDs controlled by an Arduino pro micro. I'm very happy with the final design but I have a concern about an issue with the global brightness slider in the RBG Matrix menu of sim hub.
If I set that brightness to anything over around 35-40% and display a static image such as a gear indicator from the test data editor screen it acts as if it's either over voltage or going into thermal shut down. 30-40 brightness is plenty bright but of course, my customers are going to mess with it and I would prefer not to have to include a disclaimer for this. You can see in the video (attached google photo link) that as soon as I drag the brightness slider up you'll hear the windows disconnect sound and the LED turn a yellowish color. The unit is unresponsive until it's disconnected/reconnected.
I've got plenty of open-air around the board, the refresh rate is set to 1 (not sure if this matters) and the baud rate is set to 115200 (I've tried several with the same result). The LED is wired as follows V- to GND, V+ to VCC, and I'm using data pin 6 on the board. I followed a recent guide by amstudio found here

Is there anything I may be missing regarding wiring options or any way that I can hardcode a brightness limit so that the end user won't experience this?
Thank you in advance
