This warning indicates that your Raspberry Pi is not receiving enough power, which can lead to instability, crashes, and even potential hardware damage. In this guide, we'll explain what causes undervoltage warnings, how to diagnose the issue, and the steps you can take to fix it.

An under-voltage error happens when the Raspberry Pi needs to do too much with too little power. An option to avoid this is to disable power-hungry features, like Wi-Fi, Bluetooth, or CPU overclocking.
