Product Specs

A.As for the use environment of WIFI, wireless signals are easily affected by the surrounding
environment. For example, obstacles such as trees and metals will absorb wireless signals to
some extent, so that the distance of data transmission is affected to some extent in practical
applications.
B.It is recommended that the metal enclosure be not installed in the metal enclosure as it is
shielded from radio frequency signals.
C.PCB board: as the metal will weaken the function of the antenna, when distributing the
board to the module, it is strictly prohibited to lay the floor and wire under the module
antenna. It is better if it can be hollowed out.
10.Recommended reflux temperature:
Key features of the profile:
