This question is an exact duplicate of:
this is my first electronics project that i am doing so my understanding is pretty basic. I am using an ESP8266 connected to a L293D motor driver to power a bipolar stepper motor. The issue I am having is the pin connections.
This is the microcontroller that i am using. It has 9 GPIO pins at 3.3V.
This is the driver I am using.
My first question is whether I can use the 3V out of the micro controller to power the EN pins? On the data sheet, on Recommended Operating Conditions, the High-level input voltage is a minimum of 2.3V so I guess this would be ok?
Secondly, I am trying to drive a 12V bipolar stepper motor so I am unsure whether I would need to use a second motor driver due to the lack of available pins on the driver.
