Function Description :

 
 

1、Power Input: VMS=Motor power, GND=Ground wire (all ground wire connected together), VCC=Chip power (input is 5v ,and need connect VIN when more than 6.5V )

2、Multimeter could connect current detection side of motor A in series ,to measuring current.

3、Multimeter could connect current detection side of motor B in series ,to measuring current.

4、The motor A can be connected anther motor by the output of motor A.

5、The motor B can be connected anther motor by the output of motor B.

6、Console side of motor A: EA is enable , IA is controlling reversing.

EA=1，IA=1  motor A is forward,
EA=1，IA=0  motor A is reverse,
EA=0， the motor is stopped.

7、Console side of motor B: EB is enable , IB is controlling reversing.

EB=1，IB=1  motor B is forward,
EB=1，IB=0  motor B is reverse,
EA=0， the motor is stopped.

8、Power supply port: VMS=Motor power, VCC=Chip power, VIN=Input of the regulator chip.

a) When the power supply is more than 6.5V on the entire circuit, short the VMS and VIN, then the chip and motor will share the same power (Voltage regulation by VIN , the chip’s power is 5V )

b) When the motor and chip separate power supply , if the chip’s power is 5V , the chip’s power supply need to connect VCC , if the chip’s power is more than 6.5V , the chip’s power supply need to connect VIN.

9、GND VIN input, power could be inputted by jumpwire easily.

10、VCC GND input, power could be inputted by jumpwire easily.

11、The 74hc14 inverter chip , controlling the motor’s  reversing by an IO port.
