Thank you!
I was getting this on my M5StickC-Plus, on the 10th/Oct/2022, with all the latest board/library updates.
I hope everyone else can find this thread!
For me the file I had to add those lines to was:
C:\Users[login name]\AppData\Local\Arduino15\packages\m5stack\hardware\esp32\2.0.5\boards.txt
Support have contacted me, it's an MCX connector!
The one on the LoRa module is female, so the plug you buy needs to be an MCX Male connector.
I've bought these converters for SMA plugs:

The MCX connector is exactly the same one as on most of the SDR USB sticks... https://www.amazon.co.uk/TenYua-Digital-Receiver-RTL2832U-R820T2
So if you already have a USB software defined radio hanging around, the rubbish little twig antenna can be cut off the cable, and it reused as a J antenna cable!
Thank you for this awesome tutorial.
I've got my copper wire on order, and am looking forward to putting it together. =D
Thanks to some brilliant recent inventions, there's now antenna analysers for $50, called "NanoVNA". You can use them to perfectly tune the J Pole antenna, so as much of the transmit power as possible leaves the antenna.
As my title!
Thank you everyone!

It's the odd one out when everything else I've seen is a USB-C.
Do you think there was a certain use in mind to require this kind of plug?
@m5stack Any idea when that engineer will add I2C to the M5StickC Plus? I just added it to my own copy and it only took 15 minutes. It'd make a lot more M5StickC programs compatible with the Plus too!
