Overview
PSF-B85 is an ultra low-power Wi-Fi module designed by ITEAD. The module
adopts the highly integrated Wi-Fi chip ESP8285. It features industry's highly
competitive compact packaging size and ultra-low power technology. Specially
designed for mobile devices and the Internet of Things application, it connects
physical devices to Wi-Fi wireless network to make Internet or LAN communications.
PSF-B85 has completed self-contained wireless network, with built-in 32-bit kernel
processor, on-chip SRAM, it can be used as the main control chip, but also as a WiFi
adapter. Simply apply it to other microcontroller-based designs by SPI/SDIO or
I2C/UART interface communication.

Functions
Main functions
The main function of PSF-B85 includes serial transparent transmission, PWM control,
GPIO control.
Serial transparent transmission good transmission performance, the maximum
transmission rate is 460800bps.
PWM control adjust lighting, adjust led color, adjust motor speed and much more.
GPIO control control switch, relay and more.
Operating Mode
PSF-B85 supports three operating mode:STA/AP/STA+AP.
STA mode: the module connects to Internet via a router, thus mobile phone or
computer can remote control devices via Internet.
AP mode: PSF-B85 module worked as a hotspot, which realizes directly
communication between the module and phone/ computer, enables wireless LAN
control.
STA+AP mode: this is coexistence mode, which can realize seamlessly switch via the
Internet control, easy operation.

—Reorient or relocate the receiving antenna.
—Increase the separation between the equipment and receiver.
—Connect the equipment into an outlet on a circuit different from that to which
the receiver is connected.
—Consult the dealer or an experienced radio/TV technician for help.
This equipment complies with FCC radiation exposure limits set forth for an uncont
rolled environment. This equipment should be installed and operated with minimum
distance 20cm between the radiator and your body.
