I am using Pro Micro Board with TLE5010's from Ali Express which were linked on this thread earlier.

I also used B2 going on a picture posted a couple of months ago.

I will change to B3 for /data (MISO)

I also used "F" numbered for axis. As I just assumed that it is were they should be. So maybe I can try other pins as well?

The PM staying active while plug on PM was reversed had me confused. On sleeping on it, I have realised that nothing is connected so it just sees PM. It just happened that with plug reversed there was only a pin on the VCC and nothing to ground.
