Using the ARMmite as a Daughterboard

Post by basicchip » Wed Dec 17, 2014 12:41 am

From one of the users--

I have created an ARMmite device file for the Eagle PCB design software (Eagle Rev 5.11). This enables the ARMmite to be used as a daughter card on a larger motherboard (MB) PCB. It might be useful to someone else. The Eagle library file and a photo are attached. All I/O pins and 3.3V out (for pull ups) are brought out to the MB. The wire link you see from the power socket allows the ARMmite to be powered from the MB. I used 0.1" Header Sockets on the MB with pins soldered on the ARMmite to make it a plug-in. However it could be soldered in permanently using just Header Pins and then be spaced closer to the MB.

There is a free version of the Eagle software available but it is limited in board size and number of layers.

Bruce,
I guess I'm not "up" on Eagle devices. I thought Eagle was a PCB layout package.

What would be the advantage of this, over (say) an Arduino-compatible layout?

Yes, Eagle is a PCB layout tool. The ARMmite library posted enables you to include an ARMmite as a daughter card in your board design.

And a link to the same file in the CADsoft / Eagle forum

I have updated the library for this project to line up the symbol pin naming properly with the ARM pin numbers. The package is unchanged.

The link to the Cadsoft / Eagle download is now:
