I actually just found out the answer -- it's somehow not yet implemented on the Raspberry Pi 4. The command still works on all previous Raspberry Pi devices. Since it seems to be rather difficult to find the page that even mentions this command, I'll link it as follows: Video Options in config.txt If anyone has comments on why it wouldn't be implemented yet,...

The 5V pins are already connected (and also to the on-board 5V rail - which, depending on model, is NOT "attached directly to the Pi's power supply"). Using both will make NO difference. (Strictly there will be a minor reduction in resistance, but as this is negligible it would be impossible to measure.) Note the pins do not push anything! The current ...

"What should I try?" A PROPER power supply.

The Pi requires 5V power to run. The power supplies of the Pi have an Amperage rating. ie RPi3 recommends using 3A, which contributes to the power of the Pi, and subsequently any USB devices connected to the Pi's USB ports. They will feed off this USB Power line... The Pi draws power from this line, and in itself, the more components utilized the more ...

Yes, you can power a pi with the gpio pins but you can easily DAMAGE YOUR PI. Use a 5v power supply and connect the 5v end to any 5v pin and the ground end to any ground pin on your pi.

Sorry, I don't have enough reputation to post a comment, but you may decide this is an answer. Your question is possibly a duplicate of Should I tear apart USB PSU or get a dedicated switching PSU? . That OP has the same problem - how to include a Pi power supply in an enclosure that has mains power. You could look at products of the company Meanwell, ...

The raspberry Pi Zero W consumes 230 mA with camera connected and capturing video at 1080p It further consumes 170 mA when wifi is turned on 230+170=400 mA Add 100 mA more to that just to avoid any mess. So the total power consumption by Raspberry Pi zero w is 500 mA And you want to run it for three hours that is mAh=500×3 =1500 So, you need to ...

It's absolutely about peripherals. The lowest hanging fruit for Pi 2/3b is the gpu if you are not using a display, then the usb/ethernet. The combined USB/ethernet chip consumes a couple of watts even when idle, and cannot be turned off reliably when the USB is on (I believe this may have changed with the 3b+). I believe there is a way to reduce this ...
