Quoted from Tekman:

I went ahead and ordered more LED rings and PCBs yesterday and will make another run of these again.
I gave this some thought and this will get this mod to people sooner than later while Asram56 works on his new design with SAM bus connectivity.
Ashram56 It would be great if you used my same LED ring connector pinout in your new design, so anyone that wants to change from my hardware design to your new design in development would only need to make a simple connection swap to the new board. Since all the hard work of the LED ring installation would already have been completed, it would make for an easy transition.
I should have more kits showing up in stock in as little as a couple weeks if deliveries from China go as planned.

Quoted from Tekman:

I now have five more kits in stock on my website.
