INTRODUCTION
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

Jargon buster
Plain-language definitions for the technical terms used above.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- motor driver
- An electronic circuit that lets a low-power controller switch and control a motor that needs more current than the controller pins can safely provide. Checking motor driver support matters because pumps and motors usually cannot be connected directly to a microcontroller output.
- RF
- RF means radio frequency, referring to signals used for wireless communication and other high-frequency electronics. A low-noise, stable power supply is important for RF circuits because power noise can affect signal quality and measurements.
- Shield
- An add-on board that plugs into a main controller board to give it extra features such as sensing, motor control or communication. Knowing a product supports shields helps you judge whether it can connect neatly into an existing maker-board setup.
