I am building a project consisting of a pi zero w, camera and TB6612 motor driver and two DC motors with 200-400 mA run and 1.5A hard stall. I have everything working as intended while having my pi connected to the wall and motor driver powered by AA batteries. However, the goal is obviously to make this mobile so I have been stuck on the issue on how to power the whole thing for a while now. Ideally I would love to power the whole thing with one battery like the adafruit 3.7v 6600mah battery and a T3608 voltage step up booster to get the voltage to 5v. Through researching this online I have come to find out that powering the pi and the motors with the same power source can generally cause issues. However the motor driver I am using the adafruit TB6612 has kick back diodes to protect against the inductive kick. Since I also plan on using the DC boost along with it providing me with a steady 5v I was hoping that I would indeed be able to use one battery to power the project. My question is do I still run into the same issues regardless of all this? Is powering this type of project with one battery simply not a good idea and I should stick to two separate power sources?
Thank you in advance!
