Hey, this is good info. I’ve got the pictured Amazon seller kit, and it works really bad! For the task of connecting 2.54mm “pin headers” on boards you prefer mini-pv. A little hard to search for, but does this require a special crimper of its own? As a hobbiest you don’t recommend doing your own crimping at all, and I am willing to pay money, but I do kinda need specific lengths due to a tight enclosure without much room for excess ribbon (I guess round cable might be bit better). Is there such an option? I kinda searched for it, and on electronics retailers like digikey I didn’t really see the length I wanted, though it is easy to miss stuff on there.

> A little hard to search for, but does this require a special crimper of its own? The IWISS SN-025 works well for the Mini-PV too. Which makes sense, since the dupont connectors are a near-clone designed for cheaper production. > As a hobbiest you don’t recommend doing your own crimping at all I just don't find it very enjoyable, especially getting to the point where I have tools that are actually suitable! The IWISS SN025 is fairly new[1] and before I ran across Matt's blog, reliable information on this subject was hard to find. But I mean I have after all gone through the effort of getting tools and connectors, so it's more of a medium "recommend against" rather than a "not worth doing at all". It's almost like my preference with assembling PCBs. I don't mind that as much, and am good at it, but if I can just pay someone $20 to do it for me, I'll do that instead. Except I don't think there's any services at that price point for cable harnesses.
