I power the LCD with a 5V 2A white Raspberry pi powersupply and feed the Raspberry pi with the supplied breadboard leads through GPIO pins.
I’ve got a USB keyboard and mouse, as well as a WIFI dongle stuck in the Raspberry Pi’s USB boards.
So far no ‘Low Power’ indicater has shown up.

Feeding the Raspberry Pi through the Display’s USB connector to the PI’s µ USB power in might cause the problem.
How much current does a USB 2 port provide? 500 mA max I thought.

Given the USB 2 port on the display is limited to that specification, that’s not enough to power the Pi and peripherals I’m afraid.
