Tried this with an Arduino Uno using the MotorKnob example sketch http://arduino.cc/en/Tutorial/MotorKnob Works fine and the 64:1 gearbox gives fairly high output torque. I found by experiment that the connection to Arduino is not obvious: Arduino pin 8 to in 1 (motor blue wire), pin 9 to in3 (motor yellow), pin 10 to in 2 (motor pink), pin 11 to in 4 (motor orange). My first attempt connecting the wires in sequence (8 to in1, 9 to in2 etc) resulted in the motor only turning in one direction! The motor draws about 250 mA at 5V so best to use a separate supply, remember to connect the 0V to one of the Arduino GND pins.

Instead of swapping connections around as suggested by other reviewers, I kept the connections in order and edited the sketch. I am using digital outputs D5 to D8 so used this pin assignment: #define motorPin1 5 #define motorPin2 7 #define motorPin3 6 #define motorPin4 8 I find the motor works at 15 RPM but does not work at 20 RPM; this is to be expected for a stepper motor. Torque is surprisingly good. It is not clear what the jumper adjacent to the +5V header pin is for.

Well packaged and arrived in the advertised time. The motor control boards are individually wrapped in static-resistant plastic bags which is a nice touch. Everything appears to be exactly as described. Can't wait to get these installed on the project. Would recommend.

Worked great for me on the arduino. After I used the AccelStepper Lib. (much better timing and more efficient control than the standard lib). Caveat: Only worked when I initialized the AccelStepper lib with Pin 2 and 3 swapped and Half Step Mode: AccelStepper stepper(AccelStepper::HALF4WIRE, motorPin1, motorPin3, motorPin2, motorPin4);
