Is there some kind of limitation on the Netduino?I read something that said that I can only use 4 PWM,and I need 5. What can I do to bypass it?
Using the netduino to control 5 motors.

I am not sure if there are any motor driver shields which will help you - you'll have to look around.Is there some kind of limitation on the Netduino?I read something that said that I can only use 4 PWM,and I need 5. What can I do to bypass it?
The TLC5940 can drive 16 PWMs. I had a look at this last year and produced an example for LEDs (see here for write up). It would just need a little work to get this to control motors as well.
I'm sure there will be other PWM chips around which can also be used.
Hope this help,

Hi Ben,
The traditional Netduino has 4 PWMs.
If you need more you'll want to use Netduino Go (where you can get 6 PWMs on Shield Base and even more using additional IO expansion boards). If you already have a Netduino, you can use an external PWM chip as Nevyn suggested...and then control it via SPI/I2C/etc.
