Dilwyn, please feel free to add to your wbsite if it's worth it.

Thank you Cristian. Added to my hardware docs page.

I have a good supply of these serial connectors and the special flat black cable that goes in them.

I planned to use them for the ESP32 plug in that ended up being a little problematic - mostly because the QL serial ports are crap and partly because powering it off a USB charger created an interesting ground loop.

Dave, how can I contact you? Could you send me your email via PM?
