V3 Description:
1. Using the A4988 module
2. Five different step modes
3. Adjust the maximum current output for a higher step rate.
4. Open source firmware that works with an Arduino UNO that converts G-code commands to step signals
5. Can drive four A4988 stepper motors
V4 Description:
CNC shield V4 needs to work with Nano board. It can be used as a controller expansion board for engraving machines and 3D printers. It has total 3 channel slots for A4988 stepper motor driver modules (not included) to drive 3 channels of stepper motors. Each channel of the stepper motor only needs 2 IO ports, which means that 6 IO ports are enough to manage 3 stepper motors. This shield can do a quick job of managing stepper motors in your project.
Specification:
1. 3 axis stepper motor controller
2. Compatible with micro drive laser engraving machine, three axis CNC engraving machine ,.
3. 2A can be controlled within the two-phase four-wire stepper motor.
4. Launch of the digital IO interface, easy to connect to other modules, such as ENDSTOP.
5. I2C interface has been released, it can be connected to the I2C LCD or other I2C module.
6. DC5V power interface, 7.5-12V voltage input.
7 GRBL compatible
8. Worked with adhino nano.
