Title: Wire diameter for Hand-Soldering Teensy proj.
Post by: OhManIAmWorried on Sat, 05 August 2017, 15:25:55

I have a roll of 2mm in diameter single-core wire (without resin). The plan is to use for teensy board for columns.
A guide that I read suggested to use 1mm wire or less, so I am wondering, should I search for another wire or this will do just fine.
Quite ashamed of not knowing the answer myself, please help :D

"Without resin"? You mean solder?

If it fits through the hole it should be OK.

I couldn't remember the word in Engrish. I mean that 2mm is the diameter without insulation.
Don't understand the point of hole fitting. The thing that I am asking about is will this matrix even work with the wire that thick (will the current be enough, and if the thickness is that important).

pretty much anything works unless you got some sort of sustained load.

Hi,

The stuff that turns liquid, melts, because you heat is called is "solder." When it cools it gets hard again.

Solder either has resin in the center (resin core), or not (solid). Generally I think resin core is better for hand wiring a keyboard.
Solder joins other metal parts together.

"Wire" is the stuff that never melts... it stays strong and bendable. Wire carries the electricity from place to place. Wire does not have resin.

So, it sounds like you are asking about "wire." Thick wire is used for lots of electricity. Keyboards do not need lots of electricity.
For a teensy 19ga to 22ga will probably do fine. (0.91mm to 0.64mm) 2mm seems thick to me for Teensy and keyboards.

Hope that helps.

My guess would be that 24ga to 28ga would still be fine.

USB standard is 0.5A at 5V DC.

I would use insulated wire, and in different colours if I could get it to make it easier to see what is what.
