jaredwolff Just to put this idea to bed, it is not the quality of the connection. I did tack the underside with a minimal amount of solder on each pin to allow me to desolder it later (since I wasn’t sure how I wanted to set it up yet). I just replaced the “tacked” joints with female headers and I got the same result.
I did visually check the cable as well and found it to a 1-to-1 match. The connectors are too small for any test probes I have, so I couldn’t check the connections electronically. But if you lay the cable flat there is a clear 1-to-1 pairing. So I can’t check if one of the connectors is crimped poorly.
Once I get the Zephyr setup going, I will let you know how I make out.
