yellow lightning and CPU

@rikko14 it happens

I’m assuming you have a Pi 3 or older, right?

I would power the pi via the GPIO 5V to get around the USB spec for MicroUSB that isn’t enough for the Pi.

@bkeyport I have a Pi 4 B.

@rikko14 pi4 requires the most power

@sdetweil
here is the power supply that came with the kit that I bought on Aliexpress.
I changed the power supply to a SMASUNG 5V2A and I no longer have this yellow lightning.

@rikko14 2A is close. I bought some 5A supplies
