PSF-B85

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.
