Hehe, I looked up that 'Speaker Craft Bot 1.0' and it's a 4-conductor TRRS breakout board.



Using a TRS adapter, like that EasyAdapters/Winford breakout board, above, would be simpler.

That TRRS adapter could work, but it's hit or miss - I don't think the ring sizes are standard.

But, as stated earlier in this thread, you only need tip and sleeve. If you have that SC adapter already, you may be able to make it work.

I suggest doubling up the conductors within the category cable.
