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
Software
Mboard is designed for compatible for SD libraries of Arduino.cc, and all demo codes could be downloaded directly and run it.
With embedded bootloader, Mboard is easy to use by Arduino IDE through mini USB cable. ISP of Atmega32U4 is broke out for download firmware easily.
