Great buy!
I gave this board to the robotics/mecatronics club at my middle school. The librarian has been testing it for a few weeks now and gave me a demo. I can confirm that it works great out of box, exactly as described. It offers a lot of versatility across a variety of projects and for $16 is priced really competitively.

Bonne petite carte pour la robotique !
Bon matos pour piloter des servos, c'est un circuit complet compatible avec pas mal de choses et comme d'habitude avec ce genre de matos, il faut aimer le bricolage et dans ce cas précis la robotique. La marque, je connais, fait dans le très bon rapport qualité prix !

Worked exactly as I expected
I am using it on my SO-ARM101 robot arm and have had zero issues. Very small which is great and mounts on SO-ARM101 are made for this board.
