WizFi 210/220 User Manual (WIZnet Co., Ltd.)

1. Overview

The WizFi210 family of fully certified modules offers a quick, easy, and cost effective way for

device and appliance manufacturers to add Wi-Fi capabilities to their products. The module

provides serial UART interface which enables connection to any embedded design utilizing

an 8/16/32-bit microcontroller via simple commands. The WizFi210 is an ideal solution for

organizations with limited or no Wi-Fi or RF expertise, as it not only dramatically reduces RF

design time but also removes the burden of testing and certification; allowing customers to

focus on their core application, product, or expertise. The module supports data rates up to

11 Mbps, and is compliant with 802.11b.

The WizFi210 provides customers the mean to evaluate the capabilities of ultra-low power

wireless system-on-a-chip and the Serial to Wi-Fi embedded software for Wi-Fi networks.

The Serial to Wi-Fi embedded software allows devices and appliance manufacturers to easily

add Wi-Fi capabilities to their products with minor impact on the host microcontroller

firmware.

The WizFi210 provides all the hardware and software necessary to quickly set up a serial

(UART) based link to a PC or external microcontroller.

The WizFi220 is a RF-enhanced Product. Except for [RF Output Power], the WizFi220 is

similar in management and development to the WizFi210. In other words, the WizFi220 will

consume more power but it has the improved WiFi range.

(All documents for the WizFi210 apply to the WizFi220)
