1、With the functions of overheating shutdown circuit, undervoltage lockout, and cross current protection, safe operation. 2、Adjustable potentiometer can adjust the current output, so as to obtain a higher step rate. 3、SMT placement machine manufacturing, non‑manual welding, higher yield rate, more stable performance. 4、The internal resistance of the chip is smaller, lower heat, and better heat dissipation. 5、4‑layer PCB board, better heat dissipation performance, can be used to replace old or damaged stepstick stepper motor driver module. <p class="wang-edit-text"><p class="wang-edit-text">Item Type: StepStick Stepper Motor Driver ModuleMaterial: PCBModel: DRV8825Drive Current: 2.5AWorking Voltage: DC 8.2-45VStep Resolution Subdivision: Full step, half step, 1/4 step, 1/8 step, 1/16 step and 1/32 stepPurpose: Drive stepper motorApplicable Scenarios: Suitable for driving stepper motors below 8.2V-45V 2.5A<style> .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }</style> 1 x StepStick Stepper Motor Driver Module1 x Heat Sink
