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. This board is compatible with the Arduino UNO R3. 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. 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, 8 channel Digital I/O & I2C.

Version Upgrade:
1.V2 replaces DRV8825 as stepper motor driver, higher micro stepping (1/32)
2.Increase 3.3/5V input signal switch, compatible with 3.3V microcontroller
3.Expand the driver Enable pins, support sleep mode
