Noob question - micro usb port bypass

It is possible to 'hard wire' but not recommended for physical reasons; track will fall off etc.
Fit a new uUSB socket before it destroys the pcboard.
There are five connections;

So is it relatively easy to solder a new one in? I have a soldering iron, though I'm horrible at it. Or I could hire someone to do it.

You will need a hot air desoldering tool plus experience in soldering micro electronics. If I were you, I would take/send it to a known good engineer to carry out the work.
Micro USB sockets are not expensive.

Thanks, fellas. I'll see if anyone around here can do it.

The problem with those tiny USB sockets is .. the soldering is done underside the connector, so special hot air solder is needed. Yes You can solder new wires to the PCB, but You have to fix them somehow. Perhaps a zip-tie or a knot inside the speaker will do. USB just needs Ground & 5V. A mouse cord comes to me in mind.

Bonus question: would it be simple to ID and totally kill whatever is broadcasting bluetooth in this thing? I am really electrosmog-averse, and just realized these things don't only receive but also emit radiation...grrrrrr.

Special hot air solder?? Nah, any solder can be reworked with hot air, just dial the temperature up to the right point and be patient. Less solder and more flux is a good mantra to have - use too much solder and it may wick up into connector.


Solder _paste_ might be what you are thinking of, but for rework the existing solder is usually enough, just add some more rosin as flux so it will run properly.


The best, most robust microUSB sockets have through-hole pegs for mechanical strength.


There are many different footprints for these sockets, you probably need to know the precise part number to replace it.

Hi, dragging this up again.
Can someone ID the bluetooth sender in this photo? If I pull it off will I short something? I hate eating microwaves.
The battery in this thing is 3.7 v. I had the idea to simply hook my bike's dynamo powered 5v usb charger directly to the battery and skip the whole wonky usb port..
Is there a simple way to add something in-line to reduce the voltage? I know zilch about this stuff, despite electronix class 30 years ago in high shoool, hehe.
