| Stepper Motor Shield For Arduino DRV8825 SKU:DRI0023 From Robot Wiki Stepper Motor Shield For Arduino Contents • 1 Introduction • 2 Specification • 3 Pin Out& Diagram • 4 Sample code Introduction 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 6 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, 8 channel Digital I/O & I2C. Stepper motor is a brushless DC electric motor that divides a full rotation into a number of equal steps. The motor's position can then be commanded to move and hold at one of these steps without any feedback sensor an open-loop controller , as long as the motor is carefully sized to the application in respect to torque and speed. Specification • Support 3.3V and 5V operating voltage • Suitable for and stepper motor • Board with two DRV8825 driver chip and a heat sink has been mounted. • Input DC Just power the stepper motor driver , 1.6A output current per coil • Driving Pins D4,D5,D6,D7,D8,D12 • Squeeze connector, quite easy and convenient. • 8 channel digital I/O pins & 6 channel Analog input pins • DRV8825 Microstepping bipolar stepper motor driver • Six different microstep resolutions • Compatible with Arduino UNO R3, Leonardo, Mega and other controllers, with full port extensions. Support XBee, XBee Bluetooth and RF modules, ensure that the needs of your wireless communications. • There is a switch on the board Xbee wireless interfaces corner. PROG stop wireless module, available USB programming. RUN time can use the wireless communication module. Pin Out& Diagram Stepper Motor Shield For Arduino DRV8825 • Wireless program switch o RUN Turn the Switch here to use the Xbee module o PROG Turn the Switch here to upload the sketch via USB • Motor wiring Motor wiring diagram • The new version expand two enable pins, you can enable/disable the motor driver to save the power consumption, Motor X enable pin for the D8, Motor Y enable pin for the D12, low voltage enable, the following truth table: High High High High M1 ENABLE DISENABLE ENABLE DISENABLE M2 ENABLE DISENABLE • Dip switch settings for Microstep resolution: High High High High High High High High High High High High Microstep Resolution Full step Half step 1/4 step 1/8 step 1/16 step 1/32 step 1/32 step 1/32 step • IO voltage select o Change the position of the jumper cap according to your Main board operating voltage. More details • Squeeze connector makes connection easily and quickly. • The other form of connector for XH2.54 or female headers Sample code /* This sample code is for testing the 2 stepper motors The rotation velocity can be adjusted by the code switch Microcontroller Arduino UNO */ int M1dirpin = 7 //Motor X direction pin int M1steppin = 6 //Motor X step pin int M1en=8 //Motor X enable pin int M2dirpin = 4 //Motor Y direction pin int M2steppin = 5 //Motor Y step pin int M2en=12 //Motor Y enable pin |
