Topic: 24 or 26 AWG cable for my arduino UNO ?? (Read 2973 times) previous topic - next topic

Hello , what cable do you recommned ? I will use a breadboard which supports (29-20 AWG). I think that 26 AWG cable will be more solid than 24,  is there any difference ?? Thanks

26 is thinner than 24!

I've got a batch of single-strand insulated hookup wire that's 0.6mm, which is between AWG 22 and 23, and that's just thick enough to sit solidly in Arduino female headers (designed of 0.6mm square pins), so I'd go for AWG 24 or 22 rather than 26.  For just breadboard use somewhat thinner would be fine.

oooooooh my gooood... how i messed it up ??? i looked it over wikipedia .... imagine... :P thanks a lot ! i will change the order and ask a 24 AWG thanks !

In the context of what you are doing it won't make any difference at all.

it will be too "fragile" ? do you recommend a 24 AWG ? i dont want to be afraid of making "air" with my hands to breadboard and arduino , in order not to disconnect cables...

Well I would not recommend using solder less bread board in the first place, but there is little difference I would say.

i didn't understand , sorry my english is not very good

GrumpyMike is referring to the fact that solderless breadboards can sometimes be prone to errors.......  ;)


As fas as your question goes.. the 'thicker' your wire..(lower gauge number)  the more chance it will NOT fit in the breadboard holes..

for SOLDERLESS projects/dev.. I recommend SOLID CORE wire..

for soldering projects.. I recommend using stranded wire..

Breadboards are notoriously unreliable IMO and you can spend a lot of time chasing "bugs" that are just bad connections.

They also have a quite high capacitance, this can cause things that are wrong to work and things that are right to not work. 

That said they are the easiest way to prototype, especially for a beginner.

24 + 26 AWG , fit in the holes , im sure , the cable is solid of course , but i think it will be too thin... and will go out from the holes with little movements....

So you recommend using strip board instead of breadboard ? and solder everything in place... right ?

Graynomad

I no longer prototype but go straight to a PCB. But I used breadboards for years (decades really) to good affect and they are easier than soldering onto strip board so I would say use breadboards for an initial pass at a design or if you just want to quickly experiment with a new chip etc.

Just be aware of their limitations, mostly WRT potentially unreliable connections.

Use strip boards if there's any chance the design will become permanent or if you want to use it somewhere off the workbench.

Thanks for the info , what about the cable ? 26 AWG is very thin and unstable for a breadboard ? Do you recommend buying a 24 AWG or 22 AWG instead ?

Only if it's multi-strand, not solid core.


Do you recommend buying a 24 AWG or 22 AWG instead ?


I recommend spending $2 on some proper breadboard wires with pins on the ends.
No, I don't answer questions sent in private messages (but I do accept thank-you notes...)

I can't get wire with pins because the length is not standard in my project...

this is the cable i want to buy http://www.phidgets.com/products.php?product_id=3030 ....

That's twisted pairs by the look of it, of no benefit for breadboarding. It's also 100 feet, I've not used half that much in 30 years :)

I've used packs like this in the past

22G guage and that's OK but a bit heavy at times so you could go down to 24. 26 may be too light but that's probably OK as well.
