Product Details:
CNC Shield Board Specifications:
- Version: 3.0
- Color: Red
- Size (LWH): 68 x 53 x 18 mm
- Voltage: DC 12~36V
Key Features:
- The CNC Shield Board leverages the convenience of removable A4988 or DRV8825 compatible stepper drivers.
- This versatile extension board is suitable for a variety of applications, including carving machines and 3D printer driver expansion boards.
- It is GRBL 0.8 compatible, an open-source firmware that runs on an UNO, converting G-code instructions into stepper signals.
- This board carries PWM Spindle and direction pins, providing 4-Axis support (X, Y, Z, A- can replicate X, Y, Z or establish a full 4th axis with custom firmware using pins D12 and D13).
- The compact design allows stepper motors to connect via 4-pin Molex connectors or be soldered directly onto the board.
- Note: This is an unassembled kit, requiring basic soldering skills for setup.
DRV8825 Stepper Motor Driver Specifications:
- The module’s interface pinout harmonizes with the A4988 stepper motor drive carrier, enabling it as a superior performance replacement in several applications.
- DRV8825 incorporates adjustable current limit, overcurrent, and overtemperature protection along with six micro resolution options (down to 1/32-step).
- Operating at 8.2 – 45V, it can provide up to about 1.5 per phase without a heat sink or forced air flow (up to 2.2 per volume with sufficient additional cooling).
Key Features:
- The simple step and direction control interface can connect directly to 3.3V and 5V systems.
- Supports thermal shutdown for over-temperature, over-current shutdown, and under-voltage lockout.
- Features short-to-ground and shorted-load protection.
- Offers six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step.
- The device uses a 4-layer, 2 oz copper PCB for improved heat dissipation.
- Adjustable current control allows you to set the maximum current output with a potentiometer, enabling higher voltage usage for increased step rates.
- Avails intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay).
- 45V maximum supply voltage.
- Features a built-in regulator which needs an external logic voltage supply.
Package includes:
1 CNC Shield Board
4 DRV8825 Stepper Motor Drivers.
