Pin Function Description

Circuit connection precautions:
During the use of MZ-BT02, please pay attention to avoiding the impact of interference sources such as power amplifiers, boost circuits, DC/DC circuits, etc. on the module, and avoiding the formation of a series circuit between the module power supply circuit and the high-power circuit unit, in order to improve the overall SNR of the entire machine.

Precautions

• A. Regarding the usage environment of wireless Bluetooth, wireless signals, including Bluetooth applications, are greatly affected by the surrounding environment, such as Obstacles such as trees and metals can absorb wireless signals to a certain extent, thus reducing the distance of data transmission in practical applications Affected to a certain extent.

• B. Due to the fact that all Bluetooth modules need to be paired with existing systems and placed in a shell. Due to the impact of metal casing on wireless radio frequency signals
  The number has a shielding effect. So it is recommended not to install it in a metal casing.

• C. PCB layout board: The antenna part of the Bluetooth module is a PCB antenna. Due to metal weakening the function of the antenna, it is necessary to
  When using a cloth board, it is strictly prohibited to lay or route wires under the module antenna. It would be better if it could be hollowed out.

• D. If there are batteries, metal objects, LCD screens, speakers, etc. next to the module antenna, it is required to be at least 15mm away from the antenna (as shown in the figure)

• E. When laying out, it is recommended to use a star shaped power supply line and ensure good linearity of the Bluetooth module power supply. Additionally, the ground of the BT must be separated from the ground of the operational amplifier, power amplifier, MCU, etc., and there should be no other interference ground on the lower side of the BT
• F. Do not use control cables, power cables, audio cables, MIC or other interference cables around the antenna
• G. If there are rows of seats near the module antenna and metal mesh on the outer shell that affect the signal, it is recommended to choose a professional high gain antenna

Recommended Reflux Temperature

Key features of the profile

• Initial Ramp=1-2.5℃/sec to 175℃ equilibrium
• Equilibrium time=60 to 80 seconds
• Ramp to Maximum temperature (250℃)=3℃/sec Max
• Time above liquidus temperature(217℃): 45 – 90 seconds
• Device absolute maximum reflow temperature: 250℃
