6.0 HARDWARE INSTALLATION AND GETTING STARTED 
 
6.1 Power and Motor Connection 
 
We recommend to use battery as power source to MD30C. The battery and motor can be

 

   

 

   

 

   

 

 

 

 

 

   

connected to the  

MD30C

either via the screw terminal block, or it can be soldered directly to

   

 

 

 

 

 

 

 

     

   

 

   

the pad at the bottom layer of the PCB. Make sure the battery and motor are connected to the

 

   

 

 

   

 

 

 

 

 

 

 

 

 

   

 

correct port. Connecting battery to the motor port will burn the MOSFETs on MD30C and

 

 

 

   

 

 

 

 

 

 

   

 

 

this is not covered under warranty. 
 

NOTE: 

For application where the current is > 20A, it’s recommended to solder the wire directly to

 

 

 

 

     

 

 

   

 

 

 

   

the pad at bottom layer. 

 
 

 

Battery is connected to MD30C via terminal block 

 

NOTE: 

If Switching Power Supply is being used as power source for MD30C, we recommend

 

 

 

   

 

   

 

 

 

 

 

 

parallel it with same voltage battery. This is to absorb the re-gen power from motor. DC

   

 

 

 

 

     

 

 

 

 

 

 

 

brushed motor will become generator when it is slow down and rotate by external force.
