PCB LAYOUT1)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.Introduction of SOYO Technology Development Co., Ltd.We specialize in wireless audio of 2.4G/5.8G/UHF/Bluetooth for11 years.
