Hello Mancy,

Thanks for reaching out to Intel FPGA Community.

I understand your doubt on this matter but can I reconfirm with you which is you buy the product from the same supplier or different from the first one?

And I want to inform you that Intel PSG has its authorized distributor to sale Intel devices. If you got the devices from formal distributors, you shouldn’t worry on the device authenticity as the devices must be valid units. You may find the authorized distributor list from the link below:

Marketplace Partner Program: Distributor Partner - Intel® Solutions Marketplace

Regards,

Aqid Ayman

Hello Mancy,

I also need another clarification, can you confirm that the appearance image is taken externally?
