V3 Engraver Shield 3D Printer CNC Expansion Board A4988 Driver Board for Arduino Description: and This expansion board as a driver expansion board can be used for engraving machines, 3D printers. It is a total of four slots, can drive four A4988 stepper motor. Each road stepper motors only need two IO ports. In other words, six IO ports can be well managed three stepper motors. Very convenient to use. UNO for Arduino module IO port correspondence introduction. Model # 3-01-1086 Features: Using A4988 module Five different step mode Adjust the maximum current output, so as to obtain a higher rate of step. Open source firmware that runs on an Arduino UNO that turns G-code commands into stepper signals Can drive four A4988 stepper motor.
