Does anyone know if the pi 4 deliver more power than the pi 3 or is it all about the power supply? Trying to figure a way to power the picade, 10 inch screen, usb encoder, and a 3 amp 5v amplifier.

The power supply is the main limiting factor, as far as how much current you have on offer. The official Pi 3 power supply is max 2.5A and the official Pi 4 supply is 3A max. You’re looking at either using multiple supplies, or one large capacity supply with custom wiring. I have one of these 5V 10…

Where does the 3 amp 5v amplifier get its 5V from?

Having just gone through a power delivery issue with my Pi 4 and an LED project I ended up getting one of these which I can recommend. 5V, 7A. 35W, Enclosed Power Supply - LRS-35-5 LRS-35 series 35W single output enclosed type power supply with 30mm of low profile design. Adopting the …

It is plugged into the pi. Here it is. https://www.amazon.com/dp/B077MKQJW2/?coliid=I2GG9UD1YQ3F29&colid=34NX46HTLI89D&ref_=lv_ov_lig_dp_it_im&th=1 [IMG20221004134655] So that amp, the 10 inch picade screen, and a usb encoder. I am using an older pi 3b. I was wondering is a pi 4 would make a dif…

I don’t know that the Pi 4 would make much difference in this scenario. The current from the USB ports is almost certainly limited. You might see an improvement powering the amplifier from the 5V/GND pins directly. At the end of the day it’s all going to depend on the supply to the Pi.

I think I found my small simple solution. I ordered it and it will arrive Monday. I will respond with results. I got this. Amazon.com: Plugable USB 2.0 4-Port High Speed Hub with 12.5W Power Adapter. :... Buy Plugable USB 2.0 4-Port High Speed Hub with 12.5W Power Adapter.: Hubs - Amaz…

12.5 Watts is only 2.5 Amps @ 5V. P = I x E P / V = I

Well the Rav power I used is 5v/2.4a and it worked fine.

JFYI, The Official Micro USB Power Supply is Rated for 12.5W. And the Official USB C Power Supply is rated for 15W Buy a Raspberry Pi 12.5W Micro USB Power Supply – Raspberry Pi Granted, you don’t get all those useful extra USB ports.
