Dna200 board Fire switch

[shiv]

Would I be able to use 20 gauge solid wire for the fire switch on the dna200 board. Its not a recommended size but Idk why it would be an issue. Can anyone clarify this for me...?

you could. is there a reason why so big and not stranded?

Maximim wire size per Datasheet is 22 guage so you might find that the 20 guage may not fit in the thru-holes for soldering...

 @retird is right. i just tried 20 awg stranded and although it does fit it's pain to thread it. i wouldn't recommend using 20 awg stranded let alone solid. stick with the recommended wire gauges.

Well the reason Im using 20 gauge is cuz thats what i have on hand and a lot of it! I used it earlier for extending the jxt balance connector and threading a 20g solid wire through the holes is so much easier than messing arround with stranded wire. I noticed that they dont recommend it to be silicon insulated so what i concluded was that there really shouldn't be any current running through the fire button. Thats why I was like why does it matter what wire you use as long as fits. Am i right..?

Very little current goes to the external switches (milli-amps) so use what you have on hand if you choose I guess... using 20 guage will cause no user issues except maybe fitting into thru-holes.  Solid wire has a tendency to break easier at the solder point than of stranded in my experience.  

Good luck on your build...

Well it shouldn't break because the wire actually goes through the holes haha! Fingers crossed lets see how long this baby lasts...

20ga solid is thinner than 20ga stranded, it will work fine, solid wire is not desirable because if flexed too much it can break easier than stranded, but for a fixed install like a fire switch that's no problem

Thank you turbo, thats what I was thinking haha. Much appreciated! Love this dna community too bad the fda is ready to take it away...

If you have 20gauge and your only going to use like 3cm of it you can easily strip away enough to gain access to the strands and pull out about 5 or 6 strands to make it 22 gauge
