Proposal to be included in the list "Shield boards to control several servos by PWM"
As our projects grow, we need more inputs and outputs. For robotics we use usually servos, and general microcontroller boards have between 4 to 12 PWM digital outputs, but what can we do if we need more PWM outputs?



We can use a Shield board that has 16, 32 or more PWM channels, but are all the same kind? Is any more flexible, or with a better PWM pin per $ ratio? Where can we buy it at good price?

This form is to inform about it and be published at http://letsmakerobots.com/node/39981

If you have more information or any tips don't hesitate to comment too there! Thanks!

Board's name? *
What is the name given by the manufacturer?
Manufacturer *
What is the name of the manufacturer?
How many digital PWM outputs (channels) it has? *
The board can have for example 16 or 32 PWM outputs. It depends on the board you are studying...
What is the communication interface with the main board? *
It can be I2C, RS232 or any other
Required
Does it have any preffered microcontroller platform? *
It can be designed for Arduino, Raspery Pi...
Required
What is the power supply that the board's logic needed?
The board needs a power supply for its logic process.
What is the power supply this shield can handle for servos?
Servos need power supply that can be different from logic for the board
Where can you buy the board?
Maybe you have seen the board in an online shop, please inform that here:
What is the net price for one of this board? (in American dollars: $)
If you have seen the board in a online store, please inform here the price in American dollars as all we know the currency exchange rate with our local currency
Do you know any URL with an example of application for this board?
Maybe you have seen this board in action. The application can be just a servos' test or an entire robot. The more detailed the explanation, the better for all os us ;-)   If you know several URLs please insert here all of them.
If it has a software to program it: what is the Operative System?
It can be Windows 7, 8, OSx or Linux
