PSF-A85 is a $2 ESP8285 WiFi Board for IoT and Wearables

Last month, we found out that Espressif has made a smaller version of ESP8266 targeting wearables called ESP8285, but the only development board available at the time was quite more expensive than usual at about $25. ITEAD has now released an ESP8285 module with some I/Os and an IPEX connector which they sell for just $1.99 + shipping.

More technical information include the schematics (PDF only) and ESP8285 datasheet can be found in the Wiki, which sadly does not contain any software / getting started information, but those should be the exactly same as for ESP8266.

Thanks to Nanik for the tip.

I wished they were already on the board :c

A man can dream, though

If its for Wearables, then one might assume it can run off a tiny battery, and thus take little current – both peak, and average. The Datasheet gives Typical current only. Does anyone know the max peak current ?

Just seen in the Wiki, enough consumption data given.
