How to Power A Robot Car With A Power Bank!Monday, November 07, 2016
The robot car uses the GoPiGo board which operates with voltages between 7 V and 12 V. The Raspberry Pi needs 3.3 V to operate, while each motors need between 3 V and 6 V to operate at maximum load.
4000 mAh power bank outputs around 5 V, which is far too little voltage to operate the robot car. In order to power the robot car using a power bank I figured I would need a power bank that could output at a least 12 V.
Problem is that power banks with high voltage output are far too big to mount on a small robot car. Just as I was about to give up the idea of using a power bank to power the robot car, I thought of using a USB power converter.
