2 PCS HW-134A Stepper Motor Driver
1. Features: Higher copper content, good heat dissipation performance, strong current stability
2. Manufacturing process: SMT placement machine manufacturing, non-manual welding, higher yield rate, more stable performance
Remarks:
1. A single-head printer requires 4 A4988 modules.
2. A set of dual-nozzle printer requires 5 A4988 modules.
4. Delivery list: A4988 module x 1, heat sink aluminum sheet x 1
5. Matters needing attention: Please do not plug and unplug the motor and drive when the power is on, which will easily cause the drive to burn out; also do not adjust the current when the motor is running. The correct way is to first disconnect the power supply, unplug the motor, and then power on again, adjust the potentiometer, and measure the voltage on the potentiometer until the measured voltage is the same as expected. Do not plug in the reverse drive, otherwise it will burn out the drive and even the motherboard
