11 Layout Notes
A. If there is battery, metal, LCD, loudspeaker, etc. beside the module antenna, it is required to
be at least 15mm away from the antenna
B. It is recommended to use star routing for the power supply line during layout, and ensure
that the power supply linearity of Bluetooth module is good, and the ground of BT is also
available
It must be separated from the ground of operational amplifier, power amplifier, MCU, etc., and
there shall be no other interference ground under BT
C. Do not walk around the antenna control line, power line, audio line, MIC and other
interference lines
D. If there is a row base near the module antenna and the shell has metal iron mesh which has
an impact on the signal, it is recommended to select a professional high-rise heater beneficial
antenna.
