Hi Lars, I made a short run of 20 as I was hand soldering them. I will be getting some cheaper adaptors made that I can sell larger quantities of soon, but they won’t be available for another month or so. Are there any on Amazon or Ebay you can get? I’m not familiar with the online retail options in Denmark.
You can get a cheap chinese one to tide you over. Here is an example: https://s.click.aliexpress.com/e/_A7BuDu
I hope that helps. M
