Designing a stackable shield for the Papilio DUO in Fritzing

Recommended Posts

Hi,

for my project I'm thinking about designing a stackable shield PCB that I can plug into the headers of the Papilio DUO. I looked at Fritzing as a design tool, and it has already a prepared "Arduino Mega Shield PCB".

 

The Papilio DUO Hardware Guide says that the pins of the Papilio DUO are "arranged in a Arduino Mega form factor". Does that mean that I can be confident that the pins of the Papilio DUO match exactly that of an Arduino Mega and that an Arduino Mega stackable shield will fit into the headers of the Papilio DUO?

 

Thanks

Stephan

Hello Stephan,

 

Yes, that should be the case. You should be able to use the Arduino Mega Shield PCB part in fritzing to make a shield for the Papilio DUO. The DUO will be a little bit wider then the shield you make though, I had to add a little width to accommodate the four power pins on the A and B Wing headers.

 

Jack.
