Broken power input

[Wklaus12]

Hi i have a raspberry pi and i accidently sort of broke it... Its broken because the input for the micro usb came off... As you can se it is aeperated is there anyway i can fix this? Please help

Depends...... If the connector itself is damaged then you could order a new one and solder it on, but only if the solder pads / board traces are not damaged. If there is damage to pads / traces on the board then wires and some type of connector could be soldered onto the board elsewhere such as at the polyfuse (F3) pad. This is best because the fuse will still be in the circuit.

Or your could apply 5V power to the 5V GPIO pin or 'backfeed' power through one of the standard USB ports. Doing this way however bypassed the fuse and over-voltage protection diode. Many people do this without a problem however.

The actual connector came off so how coild i fix that could i just solder it back on?... I have tried setting it back into the position and it gives no power

Looking at the micro USB on my Pis and knowing the state of my eyes to wield a soldering iron on such tiny connections, I'd feed the Pi with power via GPIO or backpower from the USB ports and cut my losses. The protection that every body raves about is a glorified fuse and as any electrician worth his salt will tell you, a fuse is mainly to protect the supply, not the appliance.

Could you tell me how to power it through the gpio or usb i dont know a ton about this stufff so please make it understandable thanks

Take a look at this:

You can run the raspi from a 5V power supply by connecting its Ground/0V and 5V wires to the same-labelled pins on the raspi.

However do not try this until you're sure you know how to make the connection. You will need some sort of electronics connectors to go onto the pins, and they must not come loose and touch nearby pins by mistake. If they do, the raspi will probably be damaged, immediately.

I suggest you have a look around and see how other people have done this first. Most of the options will need a soldering iron...

One way is to use a power supply like this:

With a USB cord like this:

Plug the cord into one of the USB connectors on the RPi. However that will use up one of the ports you might need for a mouse or keyboard.

OR
You could accomplish the same using a powered USB hub:

Power via GPIO - get some 0.1" female headers - these caught my eye because the are cheap. You can easily cut them to any length you want, these will connect to the pins on the Pi.

Then take a look here : which gives you the pinout of the GPIO connector.

Then get any solid 5V power supply and solder a lead from the GND and 5V outputs and solder them to the headers so they contact any GND and 5V power pins on the Pi. Be careful connecting them up, it will be unforgiving if you get it wrong.

I have decided that i dont want to use gpoo pins so how do u use the usb ports?

[pluggy]

You use a cheap powered hub that hasn't been doctored not to back power and you plug it into the Pis USB port (or one of them). Posh powered hubs tend to have circuitry to prevent them back powering anything thats plugged into them.

The protection that every body raves about is a glorified fuse and as any electrician worth his salt will tell you, a fuse is mainly to protect the supply, not the appliance.

Incorrect.

A fuse is designed to protect the wiring after it, not the supply leading up to the fuse. Electrical design calculations start with nominal current of the load, then selecting a fuse of greater current capacity (so normal operation won't trip it out) then selecting cable (of even higher capacity, so that it won't be damaged by any current that the fuse allows passed).

In your RPi the fuse is allowing sufficient current for normal operation but should prevent levels of current that would kill the Pi components.

My recommendation is to try to include a fuse in your power supply solution to your RPi.
