Hi!
I received the servodriver and tested it with the arduino due, but the servo is not moving. When i connect V+ the servo is twitching, but after that it's doing nothing. It is also not holding the position, i can turn the servo freely.
I tested the servo example from the adafruit homepage. On the serial monitor i can see the servonumber-output. The driver is connected to the arduino like described in the online tutorial.
The led on the servodrive is burning.
Any idea what's goning wrong?

Re: 16 channel servo driver
The Due is still very much a work in progress, and we haven't tested our boards with it. We only recommend the Due to people who are comfortable with hardware hacking.
Do you have a regular arduino, like a Uno, that you can test the servo driver with?
Also, if you post some clear, detailed pictures of your assembly and wiring, we will check it for any problems.

Re: 16 channel servo driver
Hi!
No, unfortunately i have just the due.
My assembly: I connected a 5,5V power supply to the blue terminal block (V+ and GND) of the servo driver.
The arduino is connected in this way:
Arduino Servodriver
3,3V ----------------Vcc
GND ---------------- GND
A4 ------------------ SDA
A5 ------------------ SCL
A4 and A5 means the analog in of the due.
Should this be ok?

No. The pinout of the Due is different that any other Arduino. http://arduino.cc/en/Main/ArduinoBoardDueA4 and A5 means the analog in of the due.

It has 2 i2c ports. One on pins 20, 21 and the other on pins SDA1 and SCL1.

Re: 16 channel servo driver
Fantastic! It works
On Ports 20 and 21, works fine!
Thanks for the fast helping!
