5.Note:
1>.During the application of the module,please pay attention to avoid the influence of interference sources such as power amplifier and booster circuit on the module, and avoid the power supply circuit of the module forming a series loop with the high-power circuit unit.

2>.Regarding the use environment of wireless Bluetooth, wireless signals, including Bluetooth applications, are greatly affected by the surrounding environment. Obstacles such as trees and metals will absorb wireless signals to a certain extent. Therefore, in practical applications, the distance of data transmission is affected.Certain influence.

3>.Because the Bluetooth module must be matched with the existing system and placed in the shell.Because the metal shell has a shielding effect on radio frequency signals.Therefore, it is not recommended to install in a metal enclosure.
