Product Details:
The product you are viewing is a CNC Shield Board. Here are its key details:
Version:3.0
Color: Red
Size (LWH): 68 x 53 x 18 mm
Voltage: DC 12~36 V. Please note, only the DRV8825 drivers can handle up to 36V. Keep this in mind when powering the board.
Key Features:
- The board uses detachable A4988 or DRV8825 compatible stepper drivers.
- It can function as an extension board for machine carving, or a 3D printer driver expansion board.
- It is compatible with GRBL 0.8. This is open source firmware that uses an UNO to convert G-code commands into stepper signals.
- It includes PWM Spindle and direction pins and supports 4-Axis (X, Y, Z , A). It’s possible to duplicate X,Y,Z or use a full 4th axis with custom firmware utilizing pins D12 and D13.
- The compact design allows Stepper Motors to be connected via 4 pin molex connectors or by soldering in place.
- Note that this product comes as an unsassembled kit and basic soldering skills are required.
Next up, we have the A4988 Stepper Motor Driver:
Color: Red
Size (LWH): 20 x 15 x 10 mm
The driver has a number of features to ensure its performance and safety:
- It includes thermal shutdown circuitry.
- It is equipped with crossover-current protection.
- Ground fault and load short-circuit protection are present.
- It features a compatible logic supply providing both 3.3V and 5V.
- There are five selectable step modes: full, 1/2, 1/4, 1/8 and 1/16.
Additional Features:
- The driver allows for a mix with slow current decay modes.
- It features internal UVLO and Low RDS (On) Output.
- It detects and selects automatic current decay modes automatically.
- The driver also supports synchronous rectification for low power dissipation.
- Please be aware that connecting or disconnecting a stepper motor while the driver is powered can destroy the driver.
Package includes:
1 x Engraver CNC Shield Board
4 x A4988 Stepper Motor Driver
Please be advised that the measurements of the product are manual, and therefore allow for an error of 1 ~ 3 cm.
