Hi, I would like to ask a question about PCB board design.
I want to make a one-chip PCB board using CC2650-7ID chip,
and layout and component information can be checked in ti homepage(www.ti.com/.../CC2650EM-7ID-RD)
But I want to know what kind of PCB Substrate was used on CC2650-7ID.(ex- FR4 or Rogers etc..)
Thank you for reading my inquiry and have a nice day.
