BG96 ordering codes

Can somebody indicate the difference between these two ordering codes for the BG96 module,

BG96MA-128-SGN => This seems to be LTE Cat M1 + LTE Cat NB1 + EGPRS + GNSS
BG96MC-128-SGNS => We don’t know the differences with the previous one.

We have searched through the documentation, however, could not find explanation to the ordering codes of the module.

Thank you,

BG96MA-128-SGN is BG96 HW R1.1
BG96MC-128-SGNS is BG96 HW R1.2

compare with R1.1 , The HW R1.2 add two new feature

  1. support Band25
  2. add securt boot feauture
