Hello.
I have thought about what i should do after my attempt of controlling a motor with a l293D failed (too low voltage for the motor), and i have chosen to bye another type of motor controller. Does anyone know a good controller for low voltage motors? Just the chip is much cheaper than one on a platform.
I hope someone can help me here

Well, not knowing the specs of your motor, I would suggest looking at the classic L298 dual H-bridge. It's good for 2 A and 46 V if I remember correctly. If you google it you should find any number of schematics, kits and complete boards that are reasonably priced.
Thank you very much for your reply
I will try to take a look at it and maybe buy it to see if it works correctly.
