Overview This document describes WizFi360-EVB-Shield. WizFi360-EVB-Shield is a development boa rd for experiment, test and verification of WizFi360. WizFi360-EVB-Shield can also be use d as an Arduino shield. WizFi360 is a low cost and low-power consumption industrial-grade Wi-Fi module. It is compatible with IEEE802.11 b/g/n standard and supports Soft-AP, Station and Soft-AP + Station modes. The serial port baud rate can be up to 2Mbps, which can meet the requ irement of various applications. 2. Features 2.1. WizFi360 Wi-Fi 2.4GHz 802.11 b/g/n Support Station / Soft-AP / Soft-AP + Station operation modes Support "Data pass-through" and "AT command data transfer" mode Support serial AT command configuration Support TCP Server / TCP Client / UDP operating mode Support configuration of operating channel 0 ~ 13 Support auto 20MHz / 40MHz bandwidth Support WPA_PSK / WPA2_PSK encryption Serial port baud rate up from 600bps to 2Mbps with 16 common values Support up to 5 TCP / UDP links Obtaining IP address automatically from the DHCP server (Station mode) DHCP service for Wireless LAN clients (AP mode) Support DNS for communication with servers by domain name Support "Keep-Alive" to monitor TCP connection Support "Ping" for monitoring network status Built-in SNTP client for receiving the network time Support built-in unique MAC address and user configurable 4 / 15 WizFi360-EVB-Shield Datasheet Support firmware upgrade by UART Download / OTA (via WLAN) Industrial grade (operating temperature range: -40 C ~ 85 C) CE, FCC, KC certification 2.2.
