Availability of the X-NUCLEO-IHM09M1 vs. M2

[Tedco]

1) There is no availability of the X-NUCLEO-IHM09M1 at Mouser or Digikey. Both vendors do, however, have stock of the X-NUCLEO-IHM09M2. Has the M1 been discontinued? Please let me know if there is any difference between the M1 and the M2.

2) If it turns out that the M2 replaces the M1, does SB26 still need to be removed? It’s going to be very difficult to remove SB26 without damaging the board due to its tiny size and awkward location.

3) I also need the specs and part number on the 34 pin ribbon cable that interfaces the B-G473E-ZEST1S controller board to the STEVAL-IPM30B evaluation board.

It is marked as NRND (Not Recommended for New Designs):

Which probably means they're not making any more - so once all that's in the distribution channel has gone, there'll be no more.

This doesn't tell me if the M2 is a drop-in replacement for the M1. Can someone please advise?

[Tedco]

Still need an answer. Is M2 and drop in replacement for M1

Never mind. Info already provided by Andrew. I couldn't find the "delete reply" button.
