Giới thiệu Cnc Shield + 4 X Drv8825 Driver Kit for Arduino 3D Printer
Uses removable A4988 or DRV8825 compatible stepper drivers. The extension board can be used for carving machine, 3 d printer driver expansion board GRBL 0.8 compatible. (Open source firmware that runs on an Arduino UNO that turns G-code commands into stepper signals) PWM Spindle and direction pins,4-Axis support (X, Y, Z , A-Can duplicate X,Y,Z or do a full 4th axis with custom firmware using pins D12 and D13) Compact design. Stepper Motors can be connected with 4 pin molex connectors or soldered in place. Voltage: DC 12~36 V Please note that this is an unassembled kit and Basic soldering skills are needed. DRV8825 Stepper Motor Driver The module has an interface pinout is almost the same with A4988 stepper motor drive carrier, so that it can be used as a higher performance in a pull-down menu the plates replaced in many applications. Features: 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) Colour:Color as shown Material:PCB board Package Contents: 1x CNC shielding plates 4x DRV8825 stepper motor driverOnly the above package content, other products are not included. Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
