Images are for illustration purposes only. E&OE Overview Do you want to do some projects with stepper motors such as an auto curtain, a XY Plotter, or a 3D printer? Generally, it's not an easy thing to drive stepper motor(s) with Arduino but with this Stepper Motor Shield, you can easily control 2 stepper motors via just 4 digital I/O’s. This board is compatible with the Arduino UNO R3, and get direct support with Xbee and Xbee form factor Wi-Fi, Bluetooth and RF modules. Easy connection of cables via screwless PC terminals. Each stepper motor has a code switch for adjusting driving modes, to obtain different rotational speeds. The interfaces of the board include extension 6 channel Analog I/O, 10 channel Digital I/O & I2C.The driver IC used is the most popular A4988 which is widely used in 3D printer and CNC machine. The A4988 is able to control one bipolar stepper motor at up to 2A output current per coil. With one Mega and DFRobot's Mega Expansion Shield, a 3D printer control board can be built so much eaiser. Features Easily control 2 stepper motors with only 4 digital I/OsFully compatible with Arduino UNO R3/Leonardo/Mega and supports XBee, XBee Wi-Fi, Bluetooth and RF modules6 Analog / 10 Digital & I2CScrewless connection with press and connectEach stepper motor has a switch for mode switch to obtain different rotational speed. Step modes include 1, 1/2, 1/4, 1/16.Wireless switch next to Xbee. "PROG" mode for USB uploading and "RUN" mode for wireless communicationA4988 Stepper Motor Drivers :Simple step and direction control interfaceFive different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-stepAdjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated voltage to achieve higher step ratesIntelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protectionShort-to-ground and shorted-load protection Specifications Input Voltage : 8~35VDC (Just power the stepper motor driver)Press to connect cables, quick and easyDigital I/O : D4,D5,D6,D710 Channel Digital I/O & 6 Channel Analog I/O additionA4988 Microstepping Bipolar Stepper Motor DriverAdjustable current limitingUp to 2A Output Current per coilFive different microstep resolutions (down to 1/16-step) Downloads Schematic - Stepper Motor Shield V0.3 PDF File 70.00 KB Datasheet - A4988 PDF File 383.22 KB References Product Page
