I myself already made a robot on Arduino with a slightly different engine driver, but on the same chip, but then when I did it, such as this article did not yet exist, if it were on sale, I think I would take it, since it cheaper and smaller in size.
This module has the following specifications:
1. Built on the basis of the l293 chip
2. The operating voltage is 4.5-36 V, 1A maximum, the higher is likely to simply burn out.
3. It is possible to control either two DC motors or four stepper motors, which is enough to create simple projects.
4. The module is capable of operating from voltage from 3.3 V to 5V.
5. The board size is as follows: 6 cm by 5 cm by 1.2 cm
I think many will appreciate this product, the price is small, especially fans of robotics and Arduino as a whole will like it. The link to the product is under the article.
Well, thank you all for your attention and good luck in future projects, friends!
Cost: ~ 144
