Introduction
A bluetooth circuit is the main part of a Bluetooth and contains components such as the integrated circuit, capacitors and source of power. The circuit supports wired-in audio, wireless stereo, Bluetooth module and many more. The IC contains a charger and voltage regulator. The bluetooth module contains information about the configuration and the setting.

1.Bluetooth Circuit Board
A complete Bluetooth circuit board must contain an antenna that helps to send and receive information. A bluetooth circuitry must contain at least two inductors whose job is to fine tune the antenna’s impedance to enhance performance.There is also another secondary circuit board located inside the speaker. It connects the audio line, power button, and USB power. The secondary board comes with two LEDs.
2.Bluetooth Transmitter Circuit
A Bluetooth transmitter circuit facilitates the transmission of music to the stereo. It also enables the pairing of your Bluetooth with other devices to enable you to enjoy wireless music. The circuit must have a charging system and a recyclable battery. The transmitter circuit contains a number of components including LED indicators. The circuit allows the transmitter to connect to your device immediately it is switched on. It is also designed in such a way that it can be in a standby mode until a request is sent to the transmitter.
3.Bluetooth Speaker Circuit Board
Contains the speaker as its major component. It also consists of a battery that can last for a period of between 8 to 10 hours. A lithium battery is preferred because it is long lasting. The battery contains a small circuit whose purpose is to protect it from over-current, over discharge, over-charge voltage, and short circuit.
Notice that the services offered by the speaker are handled in the main primary circuit board. The section of the circuit board consists of a voltage regulation, battery charging, Bluetooth and audio amplification. At the end of the board, you will get a microphone with volume up/down /pause control.
4.Bluetooth Audio Circuit
The Bluetooth audio circuit consists of the speaker which is normally constructed by melting the plastics to make the perforated grills. The circuit consists of two speakers and a battery. The battery has its own circuit board that protects it from over-charge voltage, over discharge and overcurrent. It also contains an audio amplifier, which supports two outputs. It also consists of the 4558 Op- Amp.
5.Diy Bluetooth Receiver Circuit
Designing a Bluetooth device circuit starts at the circuit design level. The design of the circuit depends on where the circuit is to be applied. For instance, a Bluetooth for low energy product should feature magnetometer, accelerometer, gyroscope, and sensors that measure temperature and humidity. To construct the circuit, all you need is a Bluetooth Low Energy microcontroller, a crystal oscillator, tuneable load capacitors and a 24 MHz crystal. You also require power pins, an IC, and a capacitor. You also need a clean stable voltage and power supply capacitor to filter and stabilize the power. You may make use of a decoupling capacitor and a storage reservoir with a low impedance. Note that to achieve a low impedance, it may require that you place a 1.0μF in parallel. A ferrite bead may also be included.
