Mini Mobile Robot Controller(MC40A)
if i want to control 4 motor .. can Mini Mobile Robot Controller(MC40A) do it... i notice this microcontroller can support 2 motor.. other 2 motor , i think to build their own driver...

other what is mean by Free IO pins are extended out for further development.... how many input that their have...

thank you..

I have 1 MC40A from last year 1 cent promotion

The on board Driver is L293B, you should be able to control up to 1A of current for motor. Extra 2 motor you need to use the free IO. The free IO means the part where you see the header pin at prototyping area, near to LCD.

is that the correct connection of L293B..




is that true that C is represent the free IO that ur talking about. ..
if true how many port/pin that are available(not used)..
if ur have any picture may its will help me...

thank you su much for helping me...
thank a lot.......

If you look at the User's Manual clearly, it do state that the pins under the prototyping section are the free IO pins.

Also, check the schematic.

sir .. thank for the feedback...
what i was dont's understand is connection... i mean wiring to the other 2 motor and the input so that i cant control its at the programming....

i ur have any pic pls upload here...
