Is this project still alive? Which device to pick?

Hello,

I’d love to buy a carloop device but everything is sold out in the store.

And on the github page, there’s a link to OSH park to order one but it’s the v2.1 version while the current seems to be v2.3. So which one should I take if I want to build one myself?

I also see Particle released a Photon 2. Will there be a new release for that?

Cheers,
Matt
