From USB B female to USB A male

Other Hardware General Electronics
1

Hi, I'm currently working on an electronic system that will be used outside and need to be splash proof. So I have in mind to pot the Arduino Uno into the 3D printed box that will be the head unit of the system. But I want to keep the USB connector and the power supply outside the potting.
To do this, I unweld the 5V female and the USB B female connector and replace the first one by an XT 60 connector and the second one by a USB A cable that I found in my mess.

The power supply work fine but when I plug the Franken-Arduino into my laptop the Arduino start, but he isn't recognized by my computer and that sucks.

I think I weld the 4 pins correctly.
On the back I solder the two big pins that are aside from the original USB B connector to the GND

they are really close together. are you sure you did not create any bridge or melted the thin track that was arriving there?

What do you mean by "the Arduino shut up"? Clearly you have the connections wrong. :worried:

You appear to have some rather heavy wires connected to the "barrel jack" connection. You cannot use that for 5 V.

By the way, "welding" is the wrong word in the English language for the process of soldering connections. :grin:

I made a continuity test on each wire and it's seams to be fine

Paul LED on the Arduino makes light when I plug the Arduino into my computer.

I plug a 11V battery (3S LiPo)

Yes my english is not that great.

What is your electronics background/experience ?
Do you have a DMM ?

8

No, not your English but a disturbingly common problem in translation of various non-tecnical languages. :wink:

I have a small experience into it.
Yes I have a DMM

Changing the port was maybe a bad idea. If anyone has another proposition in response to my problem.

11

the obvious first question is why did you pick the UNO ? an Arduino Nano or better the pro-mini has a much smaller foot print which makes it easier to integrate in a box and does not have the big USB port or jack, so no need for removal.

The pro-mini board can be powered through USB via the six-pin programming header or from a regulated 5V or 3.3V (depending on the model) supply applied to the VCC pin or an unregulated supply on the RAW pin.
