AD Extension board

[guerra]

Hi all,

Here in our lab we made an AD sensor expansion board for the robots and I would like to share this with you -- see the files attached to this post. Thank you Tsugawa san for working on this design!

The parts for this board are:

• ADC(AD7794)
• 10uF capacitor
• 0.1uF capacitor

The 80pin connectors should have been supplied along with the robots that you purchased.

I also uploaded the corresponding sources for interfacing this AD board to the firmware2008 CVS project:

Code:

cvs -d:pserver:anonymous@pv-league.cvs.sourceforge.net:/cvsroot/pv-league login
cvs -z3 -d:pserver:anonymous@pv-league.cvs.sourceforge.net:/cvsroot/pv-league co -P firmware2008

The folder IMU has also some sources for using this interface board to communicate with this 5 DoF IMU board from SparkFun Electronics

These can be put together in interesting ways, for example, for implementing a balancing robot (like an inverted pendulum or Segway). But the AD converter alone allows the implementation of a variety of sensors, like IR distance sensors, microphone, light sensors, etc.

Hi guerra

I saw your references of 80 pin connector, but I think cause mistake!
 I analyzed the datasheet of connector (5608), but the size of 5608 and your suggested datasheet was not similar.  In order to the size of 80 pin connector and your new board (AD board), I think 5604 is correct, is it true?
Additionally could I get this connector from Digikey? Do you know part number or …?

You're right, the parts are:

• 14 5604 080 012 829
• 24 5604 080 012 829

I'm afraid you need to contact Kyocera Connectors directly in order to purchase these.
