Single-Band (2.4 GHz) Embedded Wi-Fi b/g/n module with Integrated antenna


WE935B00 module from Wi2Wi's EM series is a best in class single-band (2.4GHz) high performance embedded Wi-Fi module. This highly integrated plug and play, embedded wifi module with chip antenna and MHF4 IPEX connector includes dedicated microcontroller, MAC, baseband, RF transceiver, power amplifier, crystal, Tx/Rx switch, filter and OTP memory for calibration data and MAC address. WE935B00 (serial to wifi module) is a complete wireless subsystem in a small form factor, featuring full 802.11 b/g/n capabilities with embedded Wireless LAN (WLAN) stack, supplicant and TCP/IP stack. By completely off-loading the external Microcontroller (MCU) from wireless and Networking Stack activities, user can dedicate the external host for application development and significantly reduce their time to market and R&D cost. This WLAN module supports UART, SPI and USB* host interfaces and comes in various operating temperatures and certified to FCC, CE and IC.
