CNC Shield Expansion Board V3.0 + 4Pcs DRV8825 Stepper Motor Driver Module with Heat Sink for Engraver 3D Printer Ramps 1.4 StepStick

Description

DRV8825 Stepper Motor Driver Module: 1.Simple step and direction control interface 2.Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step 3. Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor rated voltage to achieve higher step rates 4.45 V maximum supply voltage 5.Built-in regulator (no external logic voltage supply needed) 6.Can interface directly with 3.3 V and 5 V systems 7.Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout 8.Short-to-ground and shorted-load protection 9.4-layer, 2 oz copper PCB for improved heat dissipation 10.Exposed solderable ground pad below the driver IC on the bottom of the PCB 11.Module size, pinout, and interface match those of A4988 stepper motor driver carriers in most respects,can be used as a higher-performance drop-in replacement CNC Shield Expansion Board: 1. Version: Latest CNC Shield Version 3.0V 2. Size: 68 x 53 x 18mm / 2.67 x 2.08 x 0.7" 3. Voltage: DC 12V to 36V (only DRV8825 driver can handle up to 36V, so please consider voltage for power supply) 4. The V3.0 expansion board can be used as a drive expansion board for engraving machines, 3D printers, etc. There are a total of 4 slots for stepper motor drive modules, which can drive 4 stepper motors, and each stepper motor only needs 2 IO ports, that is to say, 6 IO ports can manage 3 steppers The motor is more convenient to use. 5. 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) Package Included: 1 x CNC Shield V3.0 Expansion Board 4 x DRV8825 Stepper Motor Driver 4 x Heatsink
