I am working on a mobile robotics personal project with a Raspberry Pi 3 Model B. The 4.5 VDC motor controllers on the rover has a no load current of 190 mA and a max load current of 250 mA. (I am using this rover here https://www.amazon.com/gp/product/B00UAXEHCO/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1).
The voltage output of a gpio pin on the raspberry pi is 3.3 V, which with my power supply is enough to get the motors running (not at full speed of course), but the current output of the gpio pin isn't nearly enough to get the motors on the rover to run. Would I need some sort of boost voltage regulator?
