Microduino-Stepper is a DMOS micro-step drive with a converter and overcurrent protection. It can be used to operate bipolar steepper motors in full, half,1/4,1/8 and 1/16 step model.Widely used in control system.

|-
|
==Feature==
*Easily to control；
*Four optional stepping modes：full, 1/2,1/4 and 1/16
*Perfect protection mechanisms:
**Overtemperature shutdown circuit, undervoltage lockout, crossover current protection;
**Ground short circuit protection, load short-circuit protection;
*Use potentiometer to adjust the current;
*Automatic current decay mode detection / selection;
*Compliance with smoke-free fire (NSNF) specification (ET package);
*The unique plug way and more space savings.

|-
|
==Specifications==
*Support bipolar stepper motor;
*Just input a pulse for the "STEP", it will drives the motor to produce micro-step. Without the need for phase sequence tables, high frequency control lines, or complex interfaces to program;
*The maximum output current can be adjusted via potentiometer, resulting in higher step rate;
*Four optional stepping modes：
**full,1/2,1/4 and 1/16；

===Electrical Specifications===
*VCC voltage：
**3.3~5V
*VMOT voltage：
**6~25V
*Maximum operating current：
**1.4A
*Under the Low current sleep mode, the current less than 10uA；
*Automatic current decay mode detection/selection;
*Overtemperature shutdown circuit, undervoltage lockout, crossover current protection;
*Ground short circuit protection, load short-circuit protection;

===Arduino library and support package===
*【AccelStepper library'''[https://github.com/adafruit/AccelStepper github download ]''' 】
*Stepper motor wiring： '''[[File:Stepper motor wiring.pdf]]'''

===Stepper motor wiring===
*Stepper motor connects with Microduino Stepper：
**Four-wire two-phase stepper motor has two sets of coils a, b, the coil resistance is very small, only several ohms. a and b are totally insulated from the group, not communicating. Measured with a multimeter, connectivity is a set;
**After measured out, a set of coils connect to OUT1A, OUT1B, another coil connects to OUT2A, OUT2B.
*By changing the MS1 & MS2 to change the stepping mode (Microduino A4982 default is 1/16 step mode);

==Application==

===Program download===
Testing Program：'''[[File:Program Test A4982.zip]]'''

===Stepper Simple Application===
*Connect the Micorduino core module,Microduino A4982 and the stepper motor.
*Prepared hardware：Microduino FT232R、Microduino Core、Microduino A4982、Four-wire two-phase stepper motor、9V~12V power；
*Prepared software：Microduino provides testing program（Arduino part）、Arduino IDE（1.0 release upper）、AccelStepper library，
*Put the downloaded library to the libraries folder of the Arduino IDE installation folder;
*Strat Ardino IDE, open the testing program, card type chooses “Microduino Core (Atmega328P@16M,5V)”, download directly;
*Use the pegboard setting up the circuit: (blue line at the bottom),as following picture:
[[File:A4982.png|thumb|600px|center|Pegboard wiring diagram]]

*Microduino Stepper drives a stepper motor：[ Test_A4982]
**External 9V or 12V power supply, the motor does not rotate in initialization state;
**Press the button, the stepper motor begins to rotate as setting speed, and LED indicator lights, reverse rotation after a few laps, the cycle repeated;
**Press the button again to close the drive, LED indicator lights off. Key detection through an interrupt, turn the switch driver.
