Is it possible to use L293D without join it as a shield to arduino, but just send direction and speed by wires? If yes, which pin I need to use L293D? Thank you! I mean this shield ![image](https://europe1.discourse-cdn.com/arduino/original/4X/9/1/2/912d4f030fa8e83306ee0bccea20eb246023e4f4.jpeg) ---

Applying 5V (connect to Vcc) or 0V (connect to GND) to the L293D inputs activates/deactivates the respective functions, as described in the [L239D data sheet](https://www.ti.com/lit/ds/symlink/l293d.pdf?ts=1758822188468&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FL293D). Use an Arduino PWM output to control motor speed. ---

ups, I didn’t mention, I mean the shield from MH Electronics, like for 4 motors which can be connected to adruino directly ---

In that case, consult the [data sheet for the shield](https://5.imimg.com/data5/PX/UK/MY-1833510/l293d-based-arduino-motor-shield.pdf) as well as the L293D data sheet. ---

You can also get simple generic modules like this. > **[Amazon.com: NOYITO L293D Mini Stepper Motor Drive Shield Module DC4.5-25V...](https://www.amazon.com/NOYITO-Stepper-DC4-5-25V-Expansion-Mega2560/dp/B07D1X8F1M)** > > Description: The Device is a mnolithic integrated high voltage,high current four channel driver.

Yes, but I already have it, so will take out l293d chip and solder it ---

So I ended up with this solution, for me more than enough. Thank you guys, all ![telegram-cloud-photo-size-2-5384144580083058572-y](https://europe1.discourse-cdn.com/arduino/original/4X/3/1/d/31d925f48c0fef3a52620f5f1b83120ff3c209e1.jpeg) ---
