DFRobot . DRI0023

<b>Introduction</b> <br> <br> Do you want to do some projects with stepper motors such as a drafting instrument, a 3D printer, an auto curtain, etc...? 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 4 digital I/O’s. This board is compatible with the Arduino UNO R3. Directly supports 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. Interfaces of the board include extension 6 channel Analog I/O, 10 channel Digital I/O &amp; I2C. <br> <br> <b>Specification</b> <br> <br> *Input Voltage: 8-35V DC(Just power the stepper motor driver) <br> *Press to connect cables, quick and easy <br> *Digital I/O:D4,D5,D6,D7 <br> *10 channel digital I/O&6 channel Analog I/O addition <br> *DRV8825 microstepping bipolar stepper motor driver <br> *Up to 1.6 A output current per coil <br> *Five different microstep resolutions (down to 1/32-step) <br><br> <b>Remind</b>: Since this product is under upgrading version, there are two versions in the inventory. You may receive the old version or the new one randomly, sorry for the inconvenience. <br> Here are new features of new version:<br> 1.The new version replaces A4988 drivers with DRV8825 ones, it has higher micro stepping (1/32 micro stepping)<br> 2. Increasing 3.3V/5V input signal switch function, compatible with 3.3V and 5V microcontroller<br> 3. Expand the driver Enable pins, support sleep mode<br> <br> <b>Shipping List</b> <br> <br> Stepper Motor Shield For Arduino (1 unit) <br>
