[Lichuang Development Board] Dashan’s balancing car

## 1. Introduction to the work

A balancing car is produced based on the development board of Lichuang Liangshan School. The main control core is GD32F470ZGT6. Adopting modular design and welded power strip, it is convenient and easy to maintain. The base plate can be externally connected to ultrasonic modules, Bluetooth modules, OLED displays, etc.
The PID has not yet been mastered. The car can currently run, but it cannot maintain balance (sad

## 2. Hardware part

1. The power supply
uses AMS1117-5.0 linear regulator IDO, 5v fixed output. The input should not exceed 12v, and should not be lower than 6.5 V.

2. Motor drive
The motor driver uses the DRV8833 module, which retains the connection between the two PWM inputs of TB6612FNG and the Liangshan school. It can also be replaced by the TB6612FNG module

3. ADC voltage collection
collects the voltage .

4.
When the motor interface is 3.3V, the positive pole of the encoder power supply and the negative pole of the encoder power supply of interface 2 must not be connected reversely, as it will cause burnout. It is okay
to connect AC1 and AC2 reversely .
The motor interface wiring method is the same. If there is a PH2.0 male and female socket, it can be changed to a socket. Mine is fixed by direct welding wires and is not suitable for replacement!

Be careful about the OLED you buy. The number of pins and pin names

6. The interfaces of other external plug-in modules
are the same as above. Be sure to pay attention to the number of pins and pin names of the module you purchased
