Động Cơ Bước Drv8825 Reprap 4 Lớp Pcb Reprap Cho Máy In 3d

Giới thiệu Động Cơ Bước Drv8825 Reprap 4 Lớp Pcb Reprap Cho Máy In 3d

Feature:
Simple step and direction control interface,
The interface can connect directly with 3.3V and 5V systems,
Support over-temperature thermal shutdown, over-current shutdown and under-voltage lockout,
Support short-to-ground and shorted-load protection,
Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step,
4-layer, 2 oz copper PCB for improved heat dissipation,
Adjustable current control support you to set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates,
Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay),
45V maximum supply voltage,
Built-in regulator (needed external logic voltage supply),

Relative to 4988 Features Advantage:
-the highest support 32 subdivision.
3. 4-layer PCB board, better heat dissipation.
-chip resistance is smaller, lower heat, better heat dissipation.

Package Include< :
1pcs StepStick DRV8825 Stepper Motor Driver,
