Get a sneak peek of the new Particle Mesh hardware: hands-on with the Xenon

I just received my Xenon and a FeatherWing OLED display. I was hoping I could plug the OLED into the top of the Xenon, but the Xenon came with pins already soldered in place. Is it possible to get a Xenon I can drop a FeatherWing onto? I'd love to make it into a wearable.
