The 802.11b/g SLIP Wireless LAN Module is a fully integrated and qualified wireless device server sub-system, designed to simplify embedding 802.11 connectivity. It is pin compatible with Siemens MC55 GPRS modules, allowing for a single PCB design to support either GPRS or Wireless LAN connectivity. Unlike other wireless modules, it integrates all necessary drivers, protocol stack, security algorithms, and a high-performance antenna. This module is designed for applications with an existing host processor running a TCP/IP stack, providing a fast and efficient way to convert a product from wired to wireless connection. It enables adding wireless internet connectivity to almost any device with a serial port and TCP/IP stack.
The EZURIO WISMCO03BI 802.11b/g Wireless LAN Module / Device Server provides a fully integrated solution for adding Wi‑Fi connectivity to devices with a serial port and TCP/IP stack. It includes an ARM7 processor, 16 MB SRAM, 64 MB flash, a high‑performance antenna, and supports both internal and external antenna configurations. The module offers a high‑speed UART (up to 921,600 bps), 12 GPIO pins, and two 10‑bit ADC inputs for versatile I/O.
Mechanically the module measures 22.8 mm × 33.8 mm × 7.6 mm and connects via a 40‑pin Hirose DF‑12 board‑to‑board connector that is pin‑compatible with Siemens MC55 GPRS and EZURIO Bluetooth modules. It operates from 3.3 V‑5 V DC, meets FCC, Industry Canada, and CE approvals, and is RoHS compliant, making it suitable for industrial M2M applications.
