Powered by a 3s lithium battery, the DRV8871 can be directly connected to a brush motor. The brush motor can use a 520 reduction motor, and each axis can be connected to an AB phase encoder. Or change the encoder interface to output comparison mode to drive the closed-loop stepper motor, or drive the brushless bldc motor through FOC through CAN communication or other control methods. In addition, the BMX055 gyroscope motion sensor chip and an SSD1351OLED driver circuit with an SPI interface are integrated to facilitate data viewing. (The wiring is a bit messy, please give me more advice)
