Questions tagged [pi-3]

For questions that apply specifically to the Raspberry Pi 3 and not other/all models.

This tag is intended for questions that are applicable to the Raspberry Pi 3 Model B which features a quad-core ARM A8 processor (64-bits) with the same 1GB of RAM and GPIO as the Pi 2 Model B, on-board Wi-Fi and Bluetooth.

This may include: power requirements; network hardware (both built-in Ethernet hardware and 2.4 GHz wireless), USB hub/ports (which is built-in with a different IC to other Raspberry Pis) and performance issues (as the processor have a default clock rate that is 33% higher than the Raspberry Pi 2B).

Undervoltage warning despite decent power supply

I found some related questions about this, yet no answer. Using a freshly bought "5V/2.1A" rated power supply, I get undervoltage warning icon on both my Raspberry Pi 3s. I measure 4.75V at the USB ports. I feel like this should not be happening.
