Product Description

Details

Overview

PSF-B85 is an ultra low-power ESP8285 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.

 PSF-B85 has onboard ceramic antenna, users can directly use, no need to design again. Please do not rub copper or connect wire below the antenna.

 If you prefer a module supports external antenna or PCB antenna, please order the PSF-A85.

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 switches, relay and more.

Operating Mode

STA mode the module connected 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 phonecomputer, enables wireless LAN control. STA+AP mode this is coexistence mode, which can realize seamlessly switch via the Internet control, easy to operate.
