【Introduction】

• ESP8266 obtains the information transmitted by the API interface in real time , displays it to the user, analyzes the data in real time, and provides feedback. Abnormal information will activate the warning system to remind the user.
• The product is made lightweight to ensure performance while reducing size and weight, and to ensure uninterrupted power supply all day long.
• The interface adopts type-c and has an automatic download circuit. It not only facilitates charging, but also facilitates code debugging/burning.
• The top of the 3D shell can be slotted into a hook , which can be hung on a school bag.
• The 3D shell uses m3 screw holes to ensure that the shell is strong, anti-falling and anti-scratch.
• The screen adopts 0.96 OLED screen (4 pins) , high definition and easy to operate.
• The circuit has multiple protection functions, diode protection circuit, filter circuit.

====================================================

【Chip solution】

Main control chip : ESP12F (esp8266) , with wifi function, which can communicate with the network server.

Power management : IP5306 , switch charging and discharging, charging and discharging function, protection function.

Transmission chip : CH340K , ultra-small size, automatic download circuit (no RX|TX pin out)

====================================================

【Code Plan】

1. Arduino : Programming the ESP8266
2. PHP : API interface (web server)

====================================================

[Automatic network distribution]

1.You can set the automatic network name in arduino.

==============================

2. When it is detected that WiFi is not connected, start automatic network configuration

Connect your mobile phone to wifi and you can configure the network.

==============================

3. Click configure wifi//hotspot please use no scanning.

==============================

4. Select wifi and enter the account password.

==============================

5. No scanning, manually fill in wifi.

==============================

6. After the connection is completed, you can restart the device.

==============================

7. Successful presentation.

====================================================

[Update progress]

• 2023-8 >>>2023-9 Design products.
• 2023-9-7 The product comes out for the first time.

====================================================

[BOM components (supports one-click purchase)]

All components have been inspected. You can place an order according to the model number, or go directly to Lichuang Mall to place an order.

(It is recommended to buy it by yourself. It will be cheaper if you buy it by yourself. The total cost is about 30-40)

====================================================

[Circuit introduction]

[Charge and discharge management circuit (IP5306)]

IP5306 is an integrated boost converter and lithium battery charging tube.
Multi-function power management SOC with management and battery power indication, providing mobile.
Power supplies provide complete power solutions.

[Automatic download circuit]

This circuit design does not lead out the RX|TX interface, and downloading can only be done through the automatic download circuit.

[Pin out]

If there are pins that need to be changed directly, 16 pin interfaces are reserved.

[Button module]

The default is D5/D6/D7, you can change others if necessary.
