Product description

Features:
1. The 3D printer accessory kit meets most needs. Including CNC V3.0, board, A4988 StepStick stepper motor module.
2. 3D printer stepper motor V3 can be used as a drive expansion board for engraving machines and 3D printers.
3. It has 4 channel slots for the A4988 stepper motor drive module for driving 4-channel stepper motors.
4. Stepper motor only needs 2 IO ports per channel, which means 8 IO ports are enough to manage 3 stepping motors.
5. This can quickly manage the stepper motor in your project.

Specification:
CNC guard:
1. PWM spindle and direction pin
2. 4-axis support (X, Y, Z, A- can copy X, Y, Z or use the custom firmware to perform the completed 4th axis using pins D12 and D13)
3. 2 x end stop for each axis (total of 6)
4. Coolant activation
5. Use a detachable A4988 or DRV8825 compatible stepper drive
6. Compact design
7. Stepper motor can be connected or soldered in place using a 4-pin connector
8. Please note that this is an unassembled kit that requires basic soldering techniques.
A4988 stepper motor driver:
1. Low RDS (on) output
2. Automatic current decay mode detection / selection
3. Mix with slow current decay mode
4. Synchronous rectification for low power consumption
5. Internal UVLO
6. current protection
7. 3.3 and 5 V compatible logic power supplies
8. Thermal shutdown circuit
9. Ground fault protection
10. Load short circuit protection
11. Five optional step modes: full, 1 / 2, 1 / 4, 1 / 8 and 1/16
