Sandy Noble's modifications to Adafruit's Motor Shield

Chatting with Sandy Noble over at the Polargraph website has been extremely helpful1  It looks like he’s added three changes to the Adafruit Motor Shield:

  • Heatsink added23
  • Breakout boards to connect the terminals to the clips for the motor leads.  However, it looks like there’s a small little component of a circular purple variety also on that board.
  • Extra pins for hooking up a cooling fan.  Sandy says he doesn’t use them any more, but it really wouldn’t be a bad idea given that it would take hours for even a simple print.
Default Series Title

  1. The photo is from Sandy Noble’s photo stream.  It says All Rights Reserved and I will happily take it down if he asks and says this is not a fair use.  Given that all of his stuff has been very open source, I’m guessing this was just a default setting. []
  2. To the H-Bridges? []
  3. Also…  Where does one get a heatsink?  How do you attach it? []
