Preorders for this next-generation module now being taken at http://www.aliexpress.com/item/ESP-32-w ... 40441.html
Price is currently $5 each with free shipping from AliExpress. From the photos, it looks like the pinouts are not breadboard-friendly, so this could be a bit challenging...
The official vendor site is www.esp32.com but am looking for other sources of info.
Please post any updates you may hear regarding this module!
