Bluetooth is a form of communication that utilizes radio frequency to connect with different devices. It can operate at 2.4 GHz frequency and is similar to the other wireless communication forms, such as Wi-Fi.
One master Bluetooth device can remotely connect to 7 other Bluetooth-enabled 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 frequencies have a range of 1 cm to 100 meters, and each connection needs approval from the devices using unique codes. Bluetooth devices can reduce energy consumption by staying idle when there is no active exchange of information.
The Bluetooth circuit boards are the main force driving wireless headsets, remote controls, wireless speakers to IoT (Internet of Things) applications. They are two-layered PCBs but have only a single plate. You will find the layers on both sides of the leaves.
What are the components of Bluetooth PCB?
A Bluetooth circuit board also contains a minimum of 2 inductors, which can fine-tune the antenna’s impedance to improve the reception and sending of information. The modules have 4 IO pins: 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.
What are the types of Bluetooth PCB?
Bluetooth boards exist in the devices and devices we use every day without careful consideration. Anything that uses a wireless connection can be using Bluetooth radio frequencies even without your knowledge.
So let us go over some typical applications of Bluetooth circuit boards.
Wireless Headsets and Earphones
Fancy listening to music on the go without the hassle of wires messing up?
Most 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.
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 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.
We don’t think twice before transferring songs or videos between devices over a Bluetooth connection. All such methods send out and receive 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.
