[Lichuang Development Board] Mini Car

Overview

Notes
1. The ultrasonic obstacle avoidance pins are reversed and the adjustment resistor is packaged incorrectly. The correct connection method should be one pin connected to 5v and three pins connected to gnd.
2. When designing the tracking infrared tube, attention should be paid to the same direction and spacing, with the outermost one in the middle. 2-3 times the distance
3. Large line widths should be used when laying out the PCB power supply. Small line widths will obviously heat up when the motor is blocked.
4. The motors can be connected with pin headers

. After the exam, the engineering and functions will be improved.

msp432 record 2-uart and display usage
The SDK explains it very clearly. It should be noted that the display can be output in different types. For now, we will use the serial port. You can also use LCD, Host, debug and other output types.
