8 Mounting Suggestion
You can refer to the following references for the mounting design of the module with an
onboard antenna (XY-MBD58B with PCB antenna).
Recommended module mounting example:
 Please do not place any metal components in blue shaded space (*1), such as signal line
and metal chassis as possible except for the mainboard while mounting the components
in *1 space on the mainboard is allowed except for no copper plating area (*2).
 (*2) This area is a routing prohibited area on the mainboard. Please do not place any copper
on any layer.
 (*3) Characteristics may deteriorate when the GND pattern length is less than 30mm. It
should be as 30 mm or more as possible.
 For the best Bluetooth range performance, the antenna area of the module shall extend 3
mm outside the edge of the mainboard, or 3 mm outside the edge of a ground plane.
