Well I'm about to buy my first pi for a joint project with my boys. I wonder if someone can tell if what I'm planning is possible?!
I'd like to use a pi zero, with picon zero pHat to make a small differential drive robot/car. I'll be looking for motors than run at around 200rpm at 6v ( I think this is about right). I plan to use 4 x rechargeable AA batteries (so 4.8v).
The pico zero seems to have lots of options as to where to draw the power from, and whether to use several power supplies or one. This is the bit I'm struggling with.
I assume the 4.8v will be close enough to 5v to run the pi zero, and the picon zero.
If the motors are too big - can they draw too much current and damage either board? Or will they drop the voltage (or current?) and just cause the pi to reset? Should I abandon this plan and up the voltage, or add a separate power supply to keep the power to the pi separate?
Any help much appreciated as I'm desperate to buy soon!
