Hi,
In my project, I´m controlling two dc motors (datasheet: https://cdn-reichelt.de/documents/datenblatt/C160/GM82.6_6v_db_en.pdf). My power source delivers 5V 3A. What motor driver would you suggest? I´m also powering my esp32 from the same power source. It should be a driver that is quite efficient, because my project is solar powered.
Thanks for your help!

I don't have much experience with regular motor drivers. Used the LM298 once and you could cook eggs on it, so I'm sure it'd be very inefficient. The datasheet you referenced says, "coming soon", but was able to find GM82.6 via a search. Says rated watts is 2.52... probably needing about 6 watts for two and the ESP32... needing about 200mm x 200mm worth of cells (not counting for driver losses) although you may need even more in Germany. I don't recall anyone on the forum going for maximum efficiency. Seems like we just use bigger batteries in our bots. But, I'm subscribed to your thread to see your progress. 👍
