MSP432 Electronic Racing Car Expansion Board

It is particularly important to note that the JY901S cannot be grounded. Grounding at the magnetometer chip area is also prohibited, as it will cause electromagnetic interference to the magnetometer, leading to inaccurate Z-axis angles. For detailed information, please refer to: FAQs (yuque.com). This MSP432 expansion board includes the following resources: 1. Serial port 3 and 4 pins are exposed. Note that jumpers for serial ports 1 and 2 need to be removed. 2. Servo expansion port. 3. RGB_LED expansion port. 4. Separate power supply for the microcontroller (to prevent damage to the MSP432). 5. TB6612 motor driver chip pins (can be directly installed using a connector, convenient and secure). 6. JY901S expansion port: Again, it is particularly important to note that the JY901S cannot be grounded. Grounding at the magnetometer chip area is also prohibited, as it will cause electromagnetic interference to the magnetometer, leading to inaccurate Z-axis angles.
