CNC Shield Board:<\/strong><\/p>\n

Version: 3.0
\nColor: Red
\nSize(L*W*H): 68 x 53 x 18 mm
\nVoltage: DC 12~36 V (At the moment only the DRV8825 drivers can handle up to 36V so please consider the operation voltage when powering the board.)<\/p>\n

Features:<\/strong><\/p>\n

1. Uses removable A4988 or DRV8825 compatible stepper drivers.
\n2. The extension board can be used for carving machine, 3 d printer driver expansion board
\n3. GRBL 0.8 compatible. (Open source firmware that runs on an Arduino-UNO that turns G-code commands into stepper signals)
\n4. 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)
\n5. Compact design. Stepper Motors can be connected with 4 pin molex connectors or soldered in place.
\n6. Please note that this is an unassembled kit and Basic soldering skills are needed.<\/p>\n

A4988 Stepper Motor Driver:<\/strong><\/p>\n

Color: Red
\nSize(L*W*H): 20 x 15 x 10 mm
\nThermal shutdown circuitry: Yes
\nCrossover-current protection: Yes
\nGround fault protection: Yes
\nLoad short-circuit protection: Yes
\nCompatible logic supply: 3.3V and 5 V
\nFive selectable step modes: full, 1\/2, 1\/4, 1\/8 and 1\/16<\/p>\n

Features:<\/strong><\/p>\n

1. Mix with slow current decay modes.
\n2. Internal UVLO and Low RDS (On) Output.
\n3. Automatic current decay mode detection\/selection.
\n4. Synchronous rectification for low power dissipation.
\n5. Warning: Connecting or disconnecting a stepper motor while the driver is powered can destroy the driver.<\/p>\n","protected":false},"excerpt":{"rendered":"
