Hi Team,
Regarding the Layout constraints for the module, We have mouting holes in PCB near the module & for that we are planning to use nylon screws instead of metal screws.
Due to space constraint & Reliable mounting of PCB , we cannot have cutout in PCB where antenna of the module resides. But we are making sure no copper is around that area.
Kindly give your comment on it.
Attached the mouting hole location & Module location in the PCB for your reference....
Regards,
Rajesh

Hi Dialog Team,
Could you reply on the query ? Is having 2.6mm Clearance from a metal screw from PCB antenna area okay ?
Attached the layout Pdf for your reference.
Appreciate your reply at the earliest.

Hi Rajesh,
Please see section 8 Design Guidelines from theDA14531 Module Datasheet. Metals close to the antenna will degrade the antenna’s performance. The amount of degradation depends on the host system’s characteristics.
Thanks, PM_Dialog
Thanks for the support!...We have managed in layout to meet the guidelines...
