This module is equipped with the L293D chip. A very powerful 4-channel driver. This board can drive four channels with 0.6A (1.2A peak) with thermal protection. Can supply a voltage from 4.5V to 25V DC (external power supply possible). With pull-down resistors to switch off the motors during startup.

It works, but you have to take into account a 1V voltage drop across both output transistors (I expected 1V on the source side because with bipolar you always have the BE junction (NPN stage), but on the sink side that is there too, and that was disappointing for my application.
