Topic: Do arduino uno shields fit into the Arduino Mega (Read 1 time) previous topic - next topic


The question speaks for itself.

I plan to order the following in addition to an arduino mega:
- http://www.pololu.com/catalog/product/2502
- http://www.jayconsystems.com/tutorial/xbee_Shield/

They both say they are compatible with Uno or Mega, but my question is will they fit into each other properly and work (Stacking the shields) will they physically fit together.

Thanks for the help, DM.


Yes they will fit.

Compatibility however is more complicated. You will have to check the schematics of both to ensure that the Arduino pins they rely on do the same things on the mega and the uno.

This is particularly a problem with SPI interfaces. Otherwise I think you should be ok.
