Ive copied it from this Makerguides tutorial. To avoid duplicating a previous topic, I will make reference to it below: Im running a simple test program just to try and turn the motor for the first time. Compatible with the Arduino UNO R3, Leonardo, Mega microcontroller Hi all, I am a beginner and this is my first post.CNC-Shield is a shield that plugs onto the Arduino development platform transforming it into a. Microstep resolutions: full, 1/2, 1/4, 1, 8, 1/16, 1/32 CNC/3-Axis Stepper Motor Shield Bundle for Arduino.Interfaces of the board include extension 6 channel Analog I/O, 8 channel Digital I/O & I2C.ġ.V2 replaces DRV8825 as stepper motor driver, higher micro stepping (1/32)Ģ.Increase 3.3/5V input signal switch, compatible with 3.3V microcontrollerģ.Expand the driver Enable pins, support sleep mode With the shield, you can drive DC motors, a stepper motor, relays, and solenoids. Each stepper motor has a code switch for adjusting driving modes to obtain different rotational speeds. The Arduino Motor Shield Rev3 is built around the L298 dual full-bridge driver, made by STMicroelectronics. This shield directly supports Xbee and Xbee form factor Wi-Fi, Bluetooth and RF modules and is easy to connect cables via screwless PC terminals. Instead of driving coils with DC signals, they are driven with PWM. This board is compatible with the Arduino UNO R3. MICROSTEP this mode is widely used in many applications as it ensures a smooth motor drive. That is a high resistance coil and your motor will not run as fast, for a given supply voltage, as a motor with a lower resistance coil. As long as there is more than 0.8 amps available there should be no problem. You should use the highest voltage allowed by the A4988. Do you want to do some projects with stepper motors such as a drafting instrument, a 3D printer, an auto curtain.? As we all know, regular stepper motors are hard to drive, but with this stepper motor shield, you can easily drive 2 stepper motors via just 6 digital I/O pins. The Pololu A4988 web page describes how to do it.
