De-Soldering Arduino Uno for use of permanent wires!?

Other Hardware General Electronics
1

Hi,

My project will be placing my arduino uno in a lock box where it will never be touched again. Is it worth de-soldering all the breadboard pin sockets and simply soldering the ones I need for a secure connection or should I just use breadboard connector cables and glue them in?

Thanks.

Doesnt worth to desolder them. They are really cheap and the electricity and time you will waste costs more.

When it comes to a permanent arduino layout, I usually make a protoboard like this

and I solder male pin header to the position of the arduino female header will be. Then, in the other side of the board I solder the ciruit point to point.

You got more reliability that way

What I do is put male headers into the female sockets and solder wires to the male pins. If your have a high-vibration environment you can use tape to hold the male headers down. One benefit is that you can easily swap out the Arduino if it fails or your need a different model (Leonardo or Mega).

Personally, I wouldn't waste an entire Arduino board by locking it away. I would rather purchase a $4-5 ATMega chip, program it on Arduino board, then either design & etch a PCB for my project, or permanently wire up a protoboard....and plug the programmed chip into it.

Just my 2¢.

Make up a minimal board like this. Then you can use your Arduino to test your next project. You can get minimal boards from places like Evil Mad Scientist:

Others have them too. Then just solder whatever pins you need. A minimal configuration only needs a couple of capacitors and a resistor or two.

You can solder wires directly to the bottom of the board without removing the headers.

You could plug in a proto-shield and attach to that. Also, various vendors sell boards
without headers installed,

My Uno cost £8 for an official one (and I have another one and an unofficial Duo), so i'm not bothered about the cost, nor that of electricity and solder. The real issue was is it worth it in terms of space saving and being permanent. I don't want to use glue or tape :slight_smile:

I also have an RFID reader that will need soldering as it is going flat and can't fit the 90 degrees into a breadboard, just wondered if it was worth soldering at the other end to the board (I haven't already made up my mind for anyone wondering :wink: )

Cheers.

Simple: If you have the space, use it as is.

OK, i've looked into solutions and there is enough room, but I don't want my friend to hear wires moving around or have them come loose. So I'm going forgo using breadboard wires and simply glue wires into the arduino connectors and solder at the RFID reader & servo ends, also allowing me to have correct length wires as I have enough colours to separate all the connections.

thanks :slight_smile:

Solder them onto the pins under the board, as fungus said.

thanks, but I forgot to mention the board will be screwed to something and will be inaccessible from the bottom, I doubt I'l change that but I might!

Thank you :slight_smile:

However that won't apply. :stuck_out_tongue:

You can solder the wires before you put the screws in...
