I want to control a small RC Car (Wltoys L939 https://www.google.com/search?q=wltoys+ ... e&ie=UTF-8) with a Raspberry Pi Zero W. The raspberry pi is currently powered with a 1200 mAh LiPo using the GIPO pins and a Powerboost 1000C (https://learn.adafruit.com/adafruit-pow ... t/overview) in between. The RC car had a 120 mAh LiPo build in, so the battery should deliver enough power to control the motor. Since by PI is already battery powered, I don't want to use any other power source other than the 1200 mAh Lipo (3,7V) to power the Pi AND the car. What's the best way to do it?
After some random searches I am still not sure whats the best approach or even how to do it. I want to power this motor ( https://www.wl-toys.com/Wltoys-L939-Pa ... 0190.html ). Should I use a H Bridge Driver (something like this: https://www.ebay.de/itm/L9110S-H-bridge ... 2453254223) or a Motor Shield for the PI? Or just a L293D? All the motor examples with the Pi or Arduino power much higher voltage motors with external, high volatge power sources.
Thanks for your suggestions.
