P2 Wi-Fi Module SMT footprint and solder specs? I can't find them anywhere. ---

A P2 footprint is avaiable for EagleCAD in Particle-Devices.lbr in hardware-libraries [https://github.com/particle-iot/hardware-libraries](https://github.com/particle-iot/hardware-libraries/tree/master/Eagle) The [reflow profile](https://docs.particle.io/reference/datasheets/wi-fi/p2-datasheet/#recommended-solder-reflow-profile) is in the datasheet. The footprint is the same as the P1, but some pin names have changed so beware of that if using a P1 footprint. ---

You are awesome! ---

I assume the pin names are updated in this library? ---

The pin names in the P2 footprint in Particle-Devices.lbr are correct. I only mentioned the P1 alternative in case you were using a different CAD program. Since the P1 has been out longer it's been converted to more formats. ---

Is there an eagle drawing of the photon 2 feathering product? It would be easier just to copy everything on it to a new pcb. ---

There should be a Photon2 footprint in Particle-Devices.lbr. ---

I want the whole circuit not just the footprint. ---

You can just use the existing featherwing footprint in your design, however note the differences in the [Argon to Photon 2 migration guide](https://docs.particle.io/hardware/migration-guides/photon-2-argon-migration-guide/) as a few pins are different. Or you can do a swap part match location with the Photon 2 footprint, however you still need to make the required changes for A5, S4 and if SPI1, if you are using that. ---
