10. PCB LAYOUT
1
）
Bluetooth antenna should be placed avoiding metal, because metal weaken
antenna function. It is forbidden to place ground or wire under Bluetooth antenna.
2
）
Metal component such as battery and chip should not overlap antenna. Module
antenna is supposed to be placed at the edge of PCB.
3
）
Signals and Bluetooth device are largely influenced by the environment. For
instance, obstacles such as trees and metal absorb signals to a certain extent. And
therefore transmission distance is often influenced in practice.
4
）
As Bluetooth module fits in certain systems placing inside cases, metal cases
should be avoided.
