5. Automated Synchronization

Internet of Things (IoT) has created hype these days and Bluetooth PCBs are an integral part of the system.

Bluetooth PCBs can be mentioned as the backbone of IoT systems. The IoT system is connecting everything through the internet and Bluetooth technology enabling users to gain full control over the devices interconnected.

For instance, the temperature of different machines in a certain facility can be checked through smartphones through a connection established via Bluetooth technology. Similarly, several other functions can also be performed to offer full control over the entire system.

Bluetooth module is the best way to integrate Bluetooth functionality in a certain device. The module is making the design process of the device very easy and comprehensive as is lowering the expenses as well.

Bluetooth PCB Module

Using the modules will increase the production cost a little but it gets economical when large-scale manufacturing is concerned.

There are different types of modules in the market and one can select based on the specification of a device.

For instance, the HC-05 Bluetooth module is used for setting up a crisp clear wireless connection. The module is supporting Bluetooth 2.0 version and is capable of transferring the data up to 2.4 GHz and it modulates the data up to 3 Mbps.

The system is a single chip and has CMOS technology incorporated along with the feature of adaptive frequency hopping. The size of the chip is also small and is about 12.7 x 27 mm.

The serial interface can be easily extended in wireless mode through this module.

When the module is connected to a computer, it uses only a single serial port, and the exchange of data is taking place through its established link.

The Bluetooth modules are usually hardware having circuit boards and enabling different devices to work in wireless connection mode with different devices.

However, a few Bluetooth modules are also coming with a USB interface and are directly plugged into the device for connecting it to other devices for the exchange of information.

Playing music through Bluetooth devices is getting normal. People play loud music through different Bluetooth devices such as speakers.

The speakers work on the basic principle of Bluetooth technology and a wireless connection is established with an audio device or smartphone for playing music.

The Bluetooth PCB module is basically a Bluetooth PCB that is installed in the devices.

The Bluetooth PCB is installed in the main circuit board and then control over the device is achieved through a wireless connection.

The Bluetooth of speakers is needed to be in ON mode to have access to the circuit board of Bluetooth PCB.

There are different segments of the circuit board which are dedicated to different functions such as charging, voltage balancing, and amplification of audio, etc.

Bluetooth PCB

Different buttons for performing functions are usually found at the backside of the Bluetooth PCB such as voice call accept/reject, microphone, play control, volume adjuster. One secondary circuit board is also affixed to the primary board for supplying power to the LEDs and power buttons.

The circuit board is usually in the form of an integrated circuit (IC) which is making the whole system of the Bluetooth circuit board.

This IC sometimes comes with a lithium-ion battery and in some cases, a voltage regulator.

The following are the main recommendations for improving the quality of Bluetooth PCBs.

1. Using Modules that are certified

The devices which are using Bluetooth technology must have certified Bluetooth modules. The use of certified modules will help the devices accelerating the development of the produce and long-life.

The use of certified modules may increase cost but in long run, it will eradicate different headaches that arise because of faults such as EMI susceptibility and antenna placement, etc.

A number of certified modules are available in the market which consists of a small ARM processor helping to enhance the performance and better connectivity.

2. Checking Devise Selection

It must be ensured that a suitable Bluetooth module is used for a specific application and it must also be ensured that the antenna of the Bluetooth module is of appropriate size and well-tuned. This mostly depends on the application type.

For instance, if the application is a simple beacon where only advertising of location or short intervals is needed, then the Bluetooth with lower energy can be cost-effective and give optimum results.

3. Removal of Higher Energy components and copper signals

When the Bluetooth module is designed, the antenna region must be kept free from all sorts of copper components and signals which are carrying abundant energy.

These areas are sometimes carrying power paths that are switched in the form of buck or boost converters.

This point is also comprised of keeping the area of the circuit board and its layers free from all polygon and plane pours.

This is the reason why most Bluetooth manufacturers are providing layout guidelines that must be followed while designing the PCB of the product which has to use a Bluetooth module.

In case if the antenna area is manually laid the ground plane is an appropriate option for keeping a very good bandwidth at the side of input for making sure that enough room is built for other elements tuning.

Ground stitched vias can also be used for prevention against the unwanted radiation from the edges of the PCB of the designed product because it may penetrate into the signals accessed and processed by Bluetooth.

In order to optimize the shape of Bluetooth PCB, the antenna must be placed near the edge and far from other components that are used for the device. In the case of using analog devices like audio signals, then it must be made sure that digital and analog ground planes are separate.
