Description

In this project, we will make an **8-channel Motor Driver Module Circuit** for motors based applications. In this circuit, we have designed a PCB for driving DC or stepper motors. By using this motor driver board **we can operate 8 DC motors or four 4-wire stepper motors at a time**. Here we have used four **L293D Motor Driver** ICs for driving motors. Here you can find the complete [DIY tutorial to build this motor driver circuit][1]. [1]: https://circuitdigest.com/electronic-circuits/motor-driver-circuit-on-pcb
