The rotation cycle of the motor can be read by on-board opto-sensor. The feature of using connector and sending logic to control rotation are shown below in figure 1. Function of IN1 and IN2 pins are directional controller. EN pin is and enable the driver Name Type Description circuit. The enable pin is active HIGH. OPA +VCC PWR Supply voltage (+5VDC) and OPB pins send signal logic HIGH to IN1, IN2 Input Rotation direction (see microcontroller when fan blade of the DC figure 1 for more detail) motor cuts the opto-sensor and logic LOW EN Input Enable motor driver otherwise. It is suitable for reading motors circuit (active high) rotation cycle. PCB size is 2.20 x 1.70 Output from opto-sensor OPA, OPB Output (logic HIGH when fan Specifications: blade cut the sensor) GND PWR Supply ground x +5VDC supply voltage x Ability to measure the speed of the motor x The motor can rotate both directions x Enable pin to shut down driver circuit for conserve the current x Direction LEDs indicator x Small and compact in size x Four mounting holes on each corner x Male and Female header inputs.
