Simple 2.4G wireless car

Overview

## The main control uses STM32F031C6T6. Use the main control board drawn by another project. According to the motor board designed on that main control board, use two dual-channel motor control modules to control the N20 motor and leave fixed holes on the PCB.## Therefore, using PCB as the carrier of the motor is not possible with 3D printer QAQ. The upper and lower board links use M3 copper pillars. When designing the main control board, there was no intention to make a motor, so there is some interference between the pin header and the motor hole. ## If the upper and lower half layers can It’s perfect to use a pin header ## The power supply is a battery pack made of 3 AA batteries with a voltage of about 4.6V ## The two wheels are too close, so it’s not good at crossing obstacles (I don’t know why this wheel is so big) QAQ)
