Hello Alexandr Korolyov and Alexey Tsitou,
I will confirm which processor is being shipped on these boards.
I reviewed a physical EVK to confirm and it has the MCIMX6Y2DVM05AA, which is the 528Mhz variant and it matches what can be found on the schematic. However, it could be that the newer boards (I’ve had this for a while now) are being shipped with the 900Mhz variant as shown on the board BOM.
I’ll let you know when I have more information.
Regards,
