If you are looking for a low-cost alternative to L293/L293d/L298/L298n motor drivers then this Dual-Channel H-Bridge L9110S could be a suitable choice. This dual-channel motor driver is a compact chip. It is compatible from 2.5V to 12V with constant current @800mA. The best feature is that L9110S Dual-Channel H-Bridge Motor Driver comes with built-in clamp diodes (output). This feature protects sensitive microcontroller-based electronics. If you are working on small robot projects then this L9119S Dual-Channel is quite helpful.

Description

There are 6 Male Pins on this the Dual-Channel motor driver. In addition, to connect the motors, you have 2x double terminals. GND and VCC are in the middle of the male terminals (3 and 4). If you have used L298 or L293, you would know the fact that those chips need separate voltage for motors. In addition, these chips also need logic voltage. But this l9110S does not need separate voltage for motors and logic voltage.

The remaining 4 pins (other than VCC and GND) are there to control the speed and direction of the motors. It works as follows:
