sudo nano /boot/config.txtĪdd below, save and close the file. But if you understand the risk, it can be disabled by the steps below. I tested it with Raspbian Stretch (November 2017 version). Description The LDF is a fast, very low drop linear regulator which operates from an input supply voltage in the range of 2.6 V to 16 V. Disabling the warning won’t make it any better. Under-voltage may cause SD card corruption and/or other problems. Replacing those with better one such as CanaKit 5V 2.5A Power Supply or HomeSpot 5V 2.4A Power Supply will most likely fix the problem. I like HomeSpot because it has ON/OFF switch, which is very convenient to power up Raspberry Pi.Ģ) Disable Under-voltage Warning (Not Recommended) If youre running a headless Raspberry Pi, theres no need to power the display circuitry, and you can save a little power by running /usr/bin/tvservice -o ( -p to re-enable). Further, CE marking is mandatory for all products covered by the Low. As such, all electronic devices with a power plug must comply, while an AAA-battery powered device is not within the scope of LVD. Ideally zero power draw once the low voltage cutoff trips, or extremely low at the very least. The Low Voltage Directive regulates electrical safety for products with an AC voltage between, or a DC voltage 75 to 1500 volts. In most cases, it’s due to the power supply and/or cable. Dont care if it utilizes a single momentary button, individual on/off buttons, or a switch. If a lightning bolt image appears in the top-right corner of the screen, it means Raspberry Pi is not getting enough voltage (4.65V according to this forum post). To prevent it from showing up, there are two options.ġ) Replace Power Supply and/or Cable (Recommended)
