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.

Onboard power supply or you.need.to use your own one?

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.
