Arduino UNO in Bangladesh The Arduino Uno is a microcontroller board based on the ATmega328 (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller.

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
The driver IC is using 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 2 A output current per coil. With one mega and DFRobot's
mega expansion shield, a 3D printer control board can be built so much eaiser.
Here are key features for A4988 stepper motor drivers
Simple step and direction control interface
Five different step resolutions: full-step, half-step, quarter-step, eighth-step,
Adjustable 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 rates
Intelligent chopping control that automatically selects the correct current
decay mode (fast decay or slow decay)
Over-temperature thermal shutdown, under-voltage lockout, and
Short-to-ground and shorted-load protection
Easily control 2 stepper motors with only 4 digital I/Os.
Fully compatible with Arduino UNO R3、Leonardo、Mega and supports
XBee，XBee Wi-Fi，Bluetooth and RF modules.
6 Analog / 10 Digital & I2C
Screwless connection with press and connect. For detailed pin mapping
please refer to product wiki.
Each 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 communication.
Input Voltage：8-35V DC(Just power the stepper motor driver)
