Bluetooth PCB is very common in our daily life. And you can find it in your smart phone other Bluetooth enabled devices. Bluetooth is a form of communication that utilizes radio frequency to connect with different devices. The paired devices exchange information serially with the master Bluetooth device. The interaction between the paired devices can be done through the master Bluetooth device, which acts as a facilitator.

Bluetooth PCB is the main force driving wireless headsets, remote controls, wireless speakers to IoT (Internet of Things) application. They are two-layered PCBs but have only a single plate. You will find the layers on both sides of the leaves.

In this passage we will discover how Bluetooth technology works.

What is the working principle of Bluetooth PCB?

The principle behind the working of a Bluetooth circuit board is straightforward. An antenna is located on the Bluetooth PCB, which receives the signal sent out by a Bluetooth device. The message is then sent to the output after being processed inside the circuit board.

Different Bluetooth profiles are used to facilitate communication between devices based on the application of the Bluetooth device. For example, the Audio/Video Remote Control Profile (AVRCP) is used for communication with audio-video devices and found in remote controls of hi-fi equipment and TVs.

What are the components of Bluetooth PCB?

A Bluetooth circuit board also contains a minimum of 2 inductors, which can fine-tune the impedance of the antenna to improve the reception and sending of information. The modules have 4 IO pins, which are the State, Enabled, communication, and power supply options. You can also find multiple resistors, diodes, and capacitors placed on the Bluetooth circuit board.

Apart from the above components, other parts such as chips, voltage regulators, and the crystal-based clock can also be found. The Bluetooth circuit board requires careful attention while assembling, especially with the antennae for its proper functioning. Bluetooth circuit boards are found within Bluetooth-enabled devices.

What are the applications of Bluetooth PCB?

Bluetooth boards exist in the devices and devices we use every day without careful consideration. Anything that uses wireless connection can be using Bluetooth radio frequencies even without your knowledge.

So let us go over some typical applications of Bluetooth circuit boards.

1.      Wireless Headsets and Earphones

Fancy listening to music on the go without the hassle of wires messing up?

Most of the wireless headsets and earphones use Bluetooth technology for the transmission of audio and voice signals. The Bluetooth circuit board is the silent performer enabling the connection between your audio device and your headset, making you listen to your favorite songs.

You can also talk over the Bluetooth connection using voice signals courtesy of the Bluetooth PCB.

2.      Cordless Keyboards and Mouse

An impressive number of wireless keyboards and mouse relies on Bluetooth circuit boards to connect to your computer and help you do your work. Earlier wireless connections were made over infra-red frequency, but Bluetooth is a far more superior alternative used these days.

Even printers, scanners, and other computer peripherals can be connected using Bluetooth technology.

Bluetooth Speakers

Bluetooth speakers are a fad these days, and everybody is carrying one. The wireless speakers have an inbuilt Bluetooth circuit board as a part of the main circuit board responsible for syncing with your audio player or smart phone.

Multimedia Transfer

We don't think twice before transferring songs or videos between devices over a Bluetooth connection. All such methods are sending out and receiving multimedia content, and other files are equipped with a Bluetooth circuit board.

The smart phone you are using also has a Bluetooth circuit board, which lets it play songs through a wireless speaker or headset and transfer files and movies from one phone to another.

Automatic Synchronization

Bluetooth connection is the spinal cord of any device which has to do with IoT. This new technology creates a bright world by connecting everything and giving you control over it.

For example, you may pick up the temperature of the machines in a factory on your smartphone over a connection established over Bluetooth frequency. Such devices use Bluetooth circuit boards for automatic synchronization and exchange of information between different touch points.
