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.
PSF-A85 specifications:
- SoC – Espressif ESP8285 Tensila WiFi SoC @ 80/160 MHz with 1MB flash
- Connectivity
- WiFi 802.11 b/g/n/d/e/i/k/r with support for STA/AP/STA+AP modes, WPA/WPA2 PSK and WEP security
- Antenna – IPEX connector (antenna not included) or “stamp hole interface”
- Expansion – 24-pin with GPIO, PWM, UART up to 460800 bps, SPI, ADC,
- Power Supply – 3.3 V
- Dimensions – 13.7 x 13.4 mm
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.

Onboard power supply or you.need.to use your own one?
@Mario
You need to provide your own 3.3V source. You’ll also need an antenna either connected to the IPEX connector, or made on the baseboard you’d design, and – if I understand correctly – connected to ANT pin.
So it’s not quite as easy to use a boards like NodeMCU or Wemos D1 mini.
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 ?
@paul
Just seen in the Wiki, enough consumption data given.
