WiFi antenna 华体会体育·（中国）股份有限公司官网 layout and Bluetooth antenna 华体会体育·（中国）股份有限公司官网
WiFi antenna 华体会体育·（中国）股份有限公司官网 layout:
We will use the ESP8266 wifi module to design a completely user-friendly wifi antenna 华体会体育·（中国）股份有限公司官网. Now we will discuss the circuit diagram. Now, as we said before, you should read the hardware design guide before designing any circuit. You can download it from Google.
First, we must design the circuit diagram of the ESP8266 development board, including all possible connections and components.
Components required for the circuit diagram:
ESP8266 WiFi module (ESP-01)
Female (partial strip)
Buttons
1KÎ © (1/4 watt) resistance
2KÎ © Resistance (1/4 watt)
100 nF capacitor
Two way slide switch
When using the ESP8266 wifi module, we must understand the pin configuration of the ESP8266 ESP-01 variant. It has 8 pins, such as VCC, GND, TX, RX, GPIO0, GPIO2, RST (reset) and CH_ PD。
Circuit board

The VCC and Chu PD pins are connected to the VCC of the power head connector, and the GND pin is connected to the GND terminal.
The RST pin is connected to the button and GND.
The GPIO2 is connected to the female GPIO head connector. On the other hand, GPIO0 is connected to the center terminal of the two-way slide switch.
The TX pin is directly connected to the TX pin of the communICation socket. The RX pin is connected to a level shifter consisting of 1 ohm and 2.2 ohm resistors.
We will design the scheme according to the circuit diagram.
The schematic diagram is complete, and you can see that it is a very SIMple design. Let's design a single-layer printed circuit board.
Now, we must send this design to the 华体会体育·（中国）股份有限公司官网 manufacturer to make 华体会体育·（中国）股份有限公司官网 our design, and then we will assemble all the components, and then we can use it.
To use it, simply connect the 3.3v power supply to the VCC and GND pins. Now, if you want to program with firmware, just switch to the programming mode position and press the RST button.
What is the Bluetooth antenna 华体会体育·（中国）股份有限公司官网?
Steps required to build the Bluetooth antenna 华体会体育·（中国）股份有限公司官网.
Design concept:
Before designing the Bluetooth antenna 华体会体育·（中国）股份有限公司官网, please read the Internet Guide carefully and create a concept about it so that you can visualize everything. Bluetooth circuit is the core of Bluetooth, including integrated circuit, capacitor, power point and other components. The operating frequency of the Bluetooth connection is 2.4 GHz. It is well known that in Bluetooth operation, there is at least one master device and one or more slave devices.
Bluetooth circuit board:
The Bluetooth circuit board must contain at least one antenna to help send and receive information. In order to improve the performance of the Bluetooth 华体会体育·（中国）股份有限公司官网, we must use at least two inductors that can adjust the antenna impedance.
We said before that the Bluetooth 华体会体育·（中国）股份有限公司官网 works in the 2.4 GHz range, which is also the RF range we use in Wi Fi technology We know that Bluetooth communication has one master device and one or more slave devices, but we must remember that the number of slave devices we can use is 7. The master device and slave devices can work within a distance of up to 10 meters Bluetooth devices always work by exchanging some unique code, so we need the consent of the owner and slave to use Bluetooth 华体会体育·（中国）股份有限公司官网 near the antenna may cause low resonant frequency. Recall that it is always recommended to keep the thickness of Bluetooth 华体会体育·（中国）股份有限公司官网 at 1.6 mm
Bluetooth transmitter circuit: Bluetooth transmitter circuit is mainly related to data transmission. It also helps to pair Bluetooth devices with other devices. It contains components that include LED indicators so that you can teach your device when to connect to other devices. The main battery is protected by a SMAll circuit, and this overcurrent will not damage the equipment. Bluetooth transmitter circuit also includes voltage regulator, battery charging unit, USB module, etc.
You can use two types of batteries to power the Bluetooth circuit board. You can use a 1A USB power supply or a LiPo battery. The instrument panel is also composed of led lights and audio devices, so you can instruct the connection status.
Some functions of the Bluetooth 华体会体育·（中国）股份有限公司官网 include:
It contains a sound device and led light, which can be used to instruct the connection status at any time.
Allows multiple devices to seamlessly transfer data using wireless connectivity.
Its design is simple and its programming is very intelligent. Users can use it without knowing it. The user interface of any Bluetooth device is very easy to use.
The Bluetooth antenna 华体会体育·（中国）股份有限公司官网's design pipeline allows you to connect to the last paired device or the nearest device in the preferred range.
How to make a Bluetooth antenna 华体会体育·（中国）股份有限公司官网:
Firstly, we must design the schematic diagram. 华体会体育·（中国）股份有限公司官网 design is one of the most challenging parts. If you are good at 华体会体育·（中国）股份有限公司官网 design, it will be the perfect choice. When designing the Bluetooth antenna 华体会体育·（中国）股份有限公司官网, we must remember some things.
First, we need a Bluetooth head, amplifier, switch, LED and a box. We must make sure that the cable does not go through the head, because this will narrow the range of Bluetooth.
Try to place the system far away from the EMItter, because if it is placed near the emitter with any pipe, it may affect the normal transmission process.
You must select the number of layers according to the number of functions to be added to the board. It is generally recommended that you select a multi-layer design for the Bluetooth 华体会体育·（中国）股份有限公司官网.
After the design is completed, send it to the 华体会体育·（中国）股份有限公司官网 manufacturer for manufacturing according to your design Then assemble all the necessary parts, and you can start
