What is difference between Turris-omnia and Turris-1.x

Hi , I am new to this turris forum,
Are Turris-omnia and Turris-1.x differs with respect to target board.??
Please give clear picture of these things


You probably don’t need to care about 1.x. They have never really been sold, only distributed to people in CZ who were taking part in a security research project. 1.x are PowerPC; Omnia is 32-bit ARM; MOX is 64-bit ARM.

Thank you so much, for the information
