ITEAD Intelligent Systems Co. Ltd PSF-B85 Manuel D’Utilisation
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.
PSF-B85 supports multiple packaging form. Supports antenna of IPEX connector
and stamp hole interface.
PSF-B85 is widely applied to smart power grid, smart transportation, smart home,
handheld devices, industrial control, etc.
Features
802.11 b/g/n/d/e/i/k/r
Support STA/AP/STA+AP mode
WPA/WPA2 PSK and WP
Built-in TCP/IP protocol stack, support multi-way TCP Client connection
Support rich Socket AT commands
Support UART/GPIO data communication interface
Built-in 32 bit MCU, also work as application processor
