Multifunctional tracking car

Project introduction:

1. Lead out all the pins of stm32 to facilitate debugging.

2. The specifications of the buck module are as follows
! [Buck module.jpg] can be adjusted according to the size of your own pressure reducing module.

3. The spare Bluetooth pins drawn out are In order to prevent design errors as a spare socket, the TXD and RXD pins can be directly connected to the lead pin headers, and can also be used for other forms of debugging.

4. The OLED module can be used to display various parameters.

5. The five-way tracking module adopts The model is as follows

**Note: The adjustments required for this tracking module are relatively demanding. You need to stick the tracking module very low to the ground. There is a kind of contact at the back that can be adjusted. Modules, you can adjust the required modules as appropriate**

6. The frame uses the 4WD frame commonly seen on Taobao

7. The ADC module can be welded as appropriate, otherwise some data may not be displayed

8. The motor uses XH2.54 *2 socket, **It is recommended not to use Dupont wire to weld on the TT motor, which may cause the motor to be unstable when plugged into the socket, or you can choose to directly weld the pin header on the XH2.54 socket to connect the Dupont wire**

9. Rudder The machine module and ultrasonic module have not been developed. Users can add corresponding functions according to the code.

10. The power module uses an ordinary 12V battery, as follows! [12V battery.jpg]
11. Two buttons are used to adjust the mode. KEY1 is to Add 1 to the mode
