Can you be more specific?Hi guys I'm not really sure how to start a new thread, I have some questions about raspberry pi stuff, any help would be good. Thanks
Here's a link to the official Pi boot problems sticky thread: https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=58151I created a thread in what I thought was the appropriate section, was it not ?
Am reaching out to see if anyone has a better understanding of the raspberry pi then myself (not hard).
Have been running retropie for a while and was all going fine then didn't try it for several months and now it won't boot.
Red power LED and green ACT LED stay constant. Have re-written the SD image and tested different power supplies but still not working, basically am asking to see if there is something I can do to test whether it is actually broken, and therefore I'll need to buy another.
I wouldn't trust that 3A step up. Assuming it can even sustainably output the current it claims, it's not going to be efficient at all. A Powerboost 1000c is about the best all in one board solution for pi projects, but it only outputs 1A at 5.2v. What do you even need 3A for anyway? A pi, screen and audio amp can pretty easily run on 1A.Hey guys looking to use 2 Panasonic 18650s to power a raspberry pi 3 and 5inch screen.
I need a booster taking 3.6v to 5v also a charging circuit (preferably one board which can do both), i would like the output to be 3A from the board to assure it will be adequate. These are what i could find but they are separate boards.
Yeah, it'd work fine as long as the cells are both at the same voltage when connected to it. Odd that it's being underpowered, what specific screen are you using?I kept getting a lightning bolt in the upper right hand corner (which meant it was underpowered ) when using the powerboost 1000C. Would the powerboost 1000C work with the 18650s?
The charge circuit will be adequate, yes. Bit slow at 1A with two cells, but it'll work fine. I might have also discovered why power consumption is an issue for you, HDMI. Using HDMI, wifi and the running LEDs on a pi 3 B increases its running current draw from 230-250ma to 480ma, and a pi 3 B+ from 350-400ma to 950ma. So depending on which model you have, that might be why.I'm using this screen
This driver board
As for the batteries they have never been used so they should be the same voltage, is there a way to determine whether the charger in the powerboost 1000C will be adequate?
