7 Application Note for Note
A. During the use of the module, please pay attention to avoid the influence of interference
sources such as power amplifier, boost circuit and DC/DC circuit on the module, and avoid the
module power supply circuit forming series circuit with high power circuit unit to reduce the
interference
B. If there are batteries, metal objects, LCD screens, horns, etc. next to the module antenna,
the distance from the antenna is required to be at least 15 mm (as shown)
C. PCB board: because metal will weaken the function of the antenna, when giving the module board,
it is strictly forbidden to lay the ground and line under the module antenna.
D. Because the metal case is shielding the RF signal, it is recommended not to install it in the
metal case
E. As for the WIFI environment, the wireless signal is easily affected by the surrounding
environment, such as trees, metals and other obstacles will absorb the wireless signal to a
certain extent, so in practical applications, the distance of data transmission is affected
to a certain extent
