Lichuang Liangshan School - Intelligent Car

LCSC Liangshan School - Intelligent Car, 10*10 board available for free board making.

The smart car
was based on LCSC's teaching materials, from circuit design to PCB layout. Due to insufficient funds, the board was modified to be 10*10, and the battery was placed directly inside without a battery holder.
Everything else was basically the same.

WiFi electric sunshade

The system uses an ESP8266 as the main controller, along with an RZ7899 motor driver chip and a geared motor to pull the steel cable, thereby causing the shade net to extend and retract.

Installation diagram. I didn't take a picture of the actual installation process with my phone, but if you're interested, leave a comment and I'll take one if someone asks.
 
 
 
 
 
Code section:
Webpage network configuration was added. The platform used is Diandeng Technology. There's a problem with the slider code; it doesn't provide real-time refresh values. I'm too lazy to fix it.
// Key code snippets:
BlinkerButton Button1("btn-l"); // Button for turning left clockwise
BlinkerButton Button2("btn-r"); // Button for reversing the motor
BlinkerButton Button3("btn-s"); // Button for stopping the motor
BlinkerNumber TEMP("temp"); // Temperature
BlinkerSlider Slider1("sld-1"); // Slider


void motorTimerCallback() {
    digitalWrite(4, LOW);
    digitalWrite(5, LOW);
    motorTimer.detach();
    BLINKER_LOG("motorStop");
}
// Motor forward rotation
void motorForward(const String &state) {
    BLINKER_LOG("get button state: ", state);
    digitalWrite(4, HIGH);
    digitalWrite(5, LOW);
    motorTimer.detach();
    motorTimer.attach_ms(motorStopInterval, motorTimerCallback);
}
//Motor reverses
void motorBackward(const String &state) {
    BLINKER_LOG("get button state: ", state);
    digitalWrite(4, LOW);
    digitalWrite(5, HIGH);
    motorTimer.detach();
    motorTimer.attach_ms(motorStopInterval, motorTimerCallback);
}
//Motor stops
void motorStop(const String &state) {
    BLINKER_LOG("get button state: ", state);
    digitalWrite(4, LOW);
    digitalWrite(5, LOW);
    motorTimer.detach();
}
void heartbeat(){
    TEMP.print(temp_read);        
}

USB Hub Expansion Dock

Use SL2.1A to create a simple USB 2.0 extension.

When using SL2.1A and adding the USB-A port,

please note: You must add a 10uF capacitor to the 1.8V and 3.3V inputs of the SL2.1A port. I didn't add one before, which caused the chip to not be recognized.

F1Clittle Mini Terminal

A mini terminal based on the Allwinner F1C200S, with... two peripherals! It's a very small but useless device.

This finger-sized terminal, based on the F1C200S, can be controlled via serial port and features a 1.14-inch screen and a programmable 0402 LED.
 
Soldering precautions:
Due to the small size of the power chip and serial port chip, it is recommended to solder the pads first before soldering the chips;
use large capacitors near the power supply interface (I personally use 22uf);
the CH343P is very close to a capacitor, so solder carefully to prevent short circuits;
the RC package is small (0402), so soldering requires care.

Regarding software, you can refer to the Lizhipai Nano (click!).
