The Arduino Robot Controller Board is a unique Arduino board which features a L298P motor driver, an XBee socket, nRF24L01+ module interface, Micro SD socket and an ATMega32U4. The bootloader of Mboard is based on Arduino Leonardo. With motor driver chip L298P, this board can drive the DC motor directly and stepper motor with software IO control. This board will add wireless as well as motor control connectivity to your projects. It’s great for anything from home automation to robot control.

Installation

Mboard can drive two DC motors at the same time. OUT1/OUT2 is completely symmetrical as OUT3/OUT4 on the board.

DC motor input has three pins, In1, In2 and EnA. In1 and In2 are digital ports which are used to control the direction of the motors, EnA is connecting with PWM port of control board to control the speed of motor.

EnA In1 In2 LED Inductor Description
0 X X C1 Off, C2 Off Free Running Motor Stop
H H L C1 On, C2 Off Forward
H L H C1 Off, C2 On Reverse
H In1=In2   C1 Off, C2 Off Fast Motor Stop
EnB In3 In4 LED Inductor Description
0 X X C3 Off, C4 Off Free Running Motor Stop
H H L C3 On, C4 Off Forward
H L H C3 Off, C4 On Reverse
H In1=In2   C3 Off, C4 Off Fast Motor Stop

And Mboard can control 4-wire stepper motor the same way as two DC motors with the signals from EnA,In1,In2 and EnB,In3,In4
