16th NXP bicycle rally group control board design solution

1. The chip adopts 80251 core, main frequency 36MHz, LQFP64; 2. TYPE-C downloader interface, can directly use TYPE-C downloader to burn the program, no need to purchase a downloader separately; 3. Special treatment of the power supply part of the microcontroller makes it more stable to use; 4. Built-in overvoltage protection, reverse connection protection, and overcurrent protection; 5. Onboard reset button, a motor module interface, four ADC acquisition interfaces, one servo interface, a linear CCD interface, an encoder interface, a reed switch interface, a gyroscope module interface, a screen interface, TYPE-C download port, Bluetooth interface, 3.3V power supply circuit, 5V power supply circuit; 6. The motor drive module interface, op amp module interface, and CCD interface use 2.0 pin headers, and other module interfaces use 2.54 standard interfaces, occupying the smallest board area, specially designed for electric motorcycles; 7. The ADC reference voltage is 5.5V system power supply.
