Replacing the microSD with something MUCH FASTER!
Today I got rid of the slow and pesky microSD card in my Pi and replaced it with something MUCH faster in my Pi LED Panel. Don’t know what my Pi LED Panel is? Check it out! This is my first video on the new channel @TechnoTimTinkers 🎉

Notes
This project was built using rpi-rgb-led-matrix
After getting the new power supply I noticed a few odd things
- When powered via hat only with the new 5v/10a AC to DC power supply, the USB drive wasn’t recognized
- When powering via USB-C 5v/5a the LED panel was too dim to display some colors so it looked distorted
I read the Pi hat documentation over and over, and no where did it mention that anything else was needed other than a large power supply. I thought for sure it was now a hardware issue and was in over my head. I dropped a message in a Discord that both Jeff Geerling and I are in and he mentioned checking out this post
In that post it suggests to add max_usb_current=1 to your config.txt.
I tested it and sure enough the Pi can now power the LED panel, the Pi, and the USB drive all from a single power supply connected to the hat. 🎉
Thanks Jeff!
