Hi,

So I am controlling two motors via bluetooth. This works fine with two 3vDC motors however they do not provide enough torque to move two trolleys I am trying to move along using a rack and pinion.

I have no been given a 48vDC motor which moves the trolley along nicely (I still need to source another). I have only tested this motor connected up to an 18v drill battery (not via the bluetooth module)

My question is will I be able to pass the 18v required to power the motor through my circuit, can my L293D IC handle 18v? I have attached the specifications of the module as I can not decipher it.

My setup is based on this tutorial

Thank you very much for reading.

The 293 datasheet that you posted the link to, says it can handle a supply voltage of Vs= 36V.

But you'll also need to check the specs of those motors for current and compare that to the datasheet's max stated 1.2 each channel.
