I have just bought a piface board and magician chassis with the aim of making a pi powered robot. However I would appreciate some help on how to run it from batteries.
The magician chassis has a battery holder for 4 AA batteries and the 2 motors that come with it are rated as 4.5V.
How would I best connect the batteries to the pi - I guess some sort of regulator would be required? Do I have to use the mini usb socket or can I connect the 5V directly to the GPIO pins.
Would it be best to use the piface relays to switch the motors on and off and if so how should they be wired up from the batteries?
can the motors be put into reverse?
Any help would be appreciated so I can get this project off and running.
thanks
Jonathan Smith
