Stepper Motor Based Rotary Encoder with Clock and Up/Down Direction Signal Output

This Module enables the users to use a stepper motor as a rotary encoder for position control and Up/Down direction control. A bipolar stepper motor can be used as a rotary sensor as it generates two channel strings of pulses by turning the shaft. The circuit provides Step pulse and Up/Down Direction signals by rotating the stepper motor shaft clockwise or counterclockwise directions. The outputs are TTL logic signals. The operating supply is 5V DC and the circuit consumes very low current.
