I’m not sure what the maker expected us to solder these to, but the spacing between the conductors is WAAAAAY to small to use with an arduino or a standard perf/proto board. My grandchildren will find these in my box of unusable parts. I have lost another week on this project, back to square one…
I’m sorry, these are not standard 0.1" spaced. They come very close, but don’t mate with other 0.1" connections.
The white version of this JST connector is much better. The wire is a heavier gauge. The tinned ends on this one makes it difficult to strip and prepare. Bring the other ones back.
