Micro USB Fix

Post by makenova »

Hello,
The micro USB end of my Samsung charger was severed in an unfortunate accident and I would like to fix it. I took off the jacket around the micro connector end to expose the solder pads and found that there are only 4 solder pads but five wires. I have soldered the four connections that I know are correct (power, ground, data- and data+) and the charger seems to be in working order. However I do not know what to do with the last wire, for now I have left it floating. I have seen some forums that say it should be soldered to ground, but they were looking for a different result. Please let me know if it is fine to leave the fifth wire floating or if it should be soldered to ground.

For a charger I expect you could leave it either unconnected or grounded. It is normally used to distinguish between master & slave, which has no meaning in a charging scenario.
