Wait — correction: Many generic “MX1616” modules actually use the variant which has standard INA, INB inputs. If your part number is MX1616L , it may lack separate inputs. Check your specific datasheet. The common variant used in hobbyist modules includes:
The motor states are determined by applying high (H) or low (L) logic levels to the input pins. Pulse Width Modulation (PWM) can be applied to the input pins to control motor speed.

When they packed the lab at the close of the semester, Mara slipped the last Mx1616 into the anti-static bag and wrote, in fine-tip pen on the outside, "For future hands. Read the notes." She taped the datasheet to the lid of the parts drawer. It was, she thought, the most human thing they had made: instructions for inventing responsibly, for listening to limits and coaxing potential into motion.

The compact module typically measures about , includes a built-in +5V regulator (LDO) for logic power, and features mounting holes (3mm diameter) for secure attachment. Check your specific datasheet
In practice, when you buy an "MX1616 module", the IC soldered on the board can be any of these variants. The performance differences are small enough that a design using one will almost always work with the others.
The table below summarizes the critical electrical characteristics from the datasheet for both the raw IC and the common pre-built module.

Stresses beyond these values may cause permanent damage.
