So like a L239D a motor shield would work?
It is L293D. The better one is L298

Could you define in what way it's better?It is L293D. The better one is L298
Both have different specs, but I wouldn't know why one would be better then the other. It depends per application.

@Supra: Normally when someone says: A is better then B, I like it when that person backs up his claim, that's all
If I quickly look at the datasheets (L293 / L298) I read that the logic input (Vcc1) of the L293 can only be 4.5-7V. The Netduino logic signals are at 3.3V, so would it work? Or maybe I'm interpreting it wrong

U r not wrong.The logic supply voltage is 7V max. Input and enable voltage is -0.3 to 7V max.
Stefan, I haven't tried it. Because i'm waiting for shield base. It should be arriving next 3 hrs today
What Mario saying that For application with motors reaching currents up to 600mA( 1.2A @ 100us) use L293.
For current up to 2A(3A @100us peak 2.5A repetitive) use L298
Remember that L293 is half w/out heat stink and L298 is dual with heat sink
