I would think this can be used with P1 as well, but the idea of pairing this with P2 seems particularly exciting.

A ARM Cortex3 alternative to ESP "unusual" Tensilica Xtensa core, this can be good.

Wow, that's a slick little WiFi module. I dug around a bit and didn't see any PCB antenna footprints available in the content out there. While I already have a few, I would think that would help people wanted to use these.

Funny that Seeed studio doesn't know what to call it so they made up a name, "Stamp Hole Expansion Interface", whereas CNX does, "12x Castellated holes". I am not sure why people don't just use the standard term for these, "castellated module".

Oh, that is shiny - significantly cheaper than the usual.

Thanks!
