【NOTES】
Only suitable for motherboards with socket stepper driver installation.
0.9-inch OLED screen, the motor current and subdivision can be modified by buttons, and displayed on the OLED, the operation is simple and convenient; in the absence of OLED, you can use the serial port to connect to the computer, and use the serial communication protocol for parameter adjustment and query

S42C V1.0 Closed Loop Driver Control Board Specification：
Maximum speed: 2000RPM
Main control chip: STM32G031G8U6, 32-bit ARM Cortex-MO+, clocked at 64MHz

【ATTENTION】
1 、When inserting the adapter board, please pay attention to the direction of the adapter board. Notice the motor and the loop chain wiring sequence!
2、For the first time, the closed-loop driver board must be connected to the motherboard with firmware, and then the encoder shall be calibrated. The calibration time will take 1-2 minutes
3、Check if the driver is installed when connecting to the computer with the serial port.
4、When the data displayed on the display or serial port is abnormal, please remove the closed-loop driver board and check if the magnet on the motor shaft is in the center position. If not, please return it to the center for recalibration.
5 、After completing the calibration, do not set it immediately after power-on. Please wait for the initialization to complete (1-2s) before setting the parameters.
6、Please do not manually turn the motor after power on.
7、The distance between the magnet at the center of the motor shaft and the core encoder should be greater than 2mm.
8 、Full stability of machine structure must be guaranteed
