Renbotics ServoShield

Vendor's Description: 

The Renbotics Servo Shield is an Arduino-compatible shield that uses two 4017 decade counters to drive up to 16 servos using only 4 pins (digital pins 6 to 9) and as little as one 8bit timer (Timer 2) in standard mode or two 16/8bit timers (Timer 1 and Timer 2 for Duemilanove or Timer 3 for Mega) in high accuracy mode. It also includes a 196 point breadboard style prototyping area.


·              16 Servo Channels

·              Convenient screw terminal for servo power supply

·              196 Point breadboard style prototyping area

·              Compatible with Arduino Duemilanove and Arduino Mega

·              Easy to use API

I thought it was a really cool shield too especially cause it's so simple and the 4017 chips only costs 0.23$ each, so I was planning to buy a bucketfull and make a SUPERVERSION of the shield...

BUT then I read THIS...

This is very nice looking shield, have to say. Simple and elegant.

 The assembly looks quite simple, are there maybe pcb schematic available if i'd like to make the board myself? 

Eagle files are now available at www.renbotics.com
there's a way you could make one that can support 30? my next project is a humanoid mech that can support 28 degrees of freedom...
The axon isn`t bad, it has easy to connect plugs at least, but for the price you can get an arduino mega plus a proto shield and still be able to save money.
Might be better to use a seperate servo controller, like the Lynxmotion SSC-32 and send commands to it from the Arduino.
Buy two and stack 'em?
you can't do that they would both want to use pin 6,7,8,9
that intercomminicate. tadaa!
