The MotorShield I bought from adafurit industries. Soldered myself, for some reason it fails to hold my 12v linear actuator, and literally burned when we tested. I have to buy another one from velleman.
Get my new Motor shield from Vellleman modules, it can handle 2.5a (max)/channal. also 3d printed free hands. here is so far what I got.
