[Resolved]- The particle relay shield

Hi all!

I have a question pertaining to the particle relay shield. My colleague and i are designing a simple board in eagle that will fit on top of the particle relay shield. We did some measurements on the particle relay shield and found that the inner row of headers is .90" apart, but what about the distance between the two outside rows??


Iā€™m confused by your measurements.

The inner row is where the Photon plugs in, and those are 0.7" apart, per the [Photon land pattern] (https://docs.particle.io/datasheets/photon-datasheet/#recommended-pcb-land-pattern-photon-with-headers-).

The headers on the relay shield are in a 0.1"x0.1" pattern, so the outer row should be 0.9" apart.

Measuring it, that seems to be the case.


@Johnoy, did you know you can get the eagle cad files for all the shields here:


Thanks works perfectly!
