This compact Infrared robot controller is based on Arduino Nano and L298 H-Bridge. The Nano shield can be used in various DC Motor driver applications using infra-red remote control or speed controller using trimmer potentiometer and direction control with help of slide switch.   The board can drive two small size DC-Motors with current rating up to 1A each. Board also has jumpers to drive single DC Motor up to 2A. Additional 10K trimmer potentiometer and slide switch provided for DC Motor speed and direction control. The L298 IC mounted under the PCB so board can be mounted on heat sink directly in horizontal position. Screw terminal provided to connect motors. Circuit requires 7-18V DC , close the Jumper J-5V to power up the Arduino Nano. Close J1, J2, J3, J4, J5, jumpers for single motor operations.
