A variety of applications utilize Bluetooth, including:
- Beacons used in shopping malls
- Eddystone frames for industrial sensing applications
- Headsets and audio/stereo products
- Remote peripheral devices such as video game controller or computer mice/keyboards
- Home automation systems
- Wireless consumer electronics applications including cameras, printers and phones
Each application incorporates the same common Bluetooth technology, but utilizes it differently and depending on the connection type, it’s up to the design engineer to incorporate basic principles to optimize signal integrity and overall device effectiveness.
What are the components for 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.
It is what a Bluetooth circuit board looks like. Like we have already said, Bluetooth circuit boards are found within Bluetooth-enabled devices. In the next chapter, we will explore some of the practical applications of Bluetooth circuit boards.
What are the recent technologies of Bluetooth PCB?
Bluetooth, like all technology, is steadily evolving as the demand for it increases. Also, currently, the newest Bluetooth standard is version 5.0, which began in 2016. Like cellular transmission standards increase, so does Bluetooth technology. Furthermore, the technology, as a whole, uses classifications to signify the wireless range of the device. More specifically, there are three classifications of Bluetooth, and they are as follows;
Class 1 signifies a range of 328 feet (maximum). For example, laptops and PCs.
Class 2 indicates a range of 33 feet (maximum), and it is the most common class on the market — for example, smart phones and Bluetooth headphones.
Class 3 designates a range of approximately 3.3 feet (maximum) — for example, small devices like an ECG (electrocardiogram) stress test wireless medical device.
