HiSKY CNC Shield Contoller Kits for 3D Printer, CNC Shield Expansion Board V3.0 A4988 Stepper Motor Driver with Heatsink (Red)

CNC Shield Board:
1>PWM Spindle and direction pins
2>2 x End stops for each axis (6 in total)
3>Coolant enable
4>Uses removable A4988 or DRV8825 compatible stepper drivers
5>Compact design
6>Stepper Motors can be connected with 4 pin molex connectors or soldered in place
7>Runs on 12-36V DC. (At the moment only the DRV8825 drivers can handle up to 36V so please consider the operation voltage when powering the board.)
8>Please note that this is an unassembled kit and Basic soldering skills are needed

DRV8825 Stepper Motor Driver:
1)*Suitable for driving below 8.2V ~ 45V 2.5A stepper motor
2)*Six different stepping resolutions: full, half, 1 / 4,1 / 8,1 / 16,1 / 32.
3)*A simple steps and direction control interface.
4)*Adjustable potentiometer can adjust the maximum output current, resulting in higher step rate.
5)*Automatic current decay mode detection / selection.
6)*Thermal shutdown circuit, undervoltage lockout, crossover current protection.
7)*Ground short-circuit protection and load short-circuit protection.
8)*DRV8825:20*15*11mm/approx 0.79*0.59*0.43inch(L-W-H) .
9)*Heat Sink: 9*9*5mm/approx 0.35*0.35*0.2inch(L-W-H).
10)*Net weight: 4g

A4988 Stepper Motor Driver:
1>Low RDS (On) Output
2>Automatic current decay mode detection / selection
3>Mix with slow current decay modes
4>Synchronous rectification for low power dissipation
5>Internal UVLO
6>Crossover-current protection
7>3.3 and 5 V compatible logic supply
8>Thermal shutdown circuitry
9>Ground fault protection
10>Load short-circuit protection
11>Five selectable step modes: full, 1/2, 1/4, 1/8 and 1/16
12>Warning: Connecting or disconnecting a stepper motor while the driver is powered can destroy the driver. (More generally, rewiring anything while it is powered is asking for trouble)
