WIFI232-A2, Industrial High Performance WiFi Module

Description of product

DESCRIPTION
UART WiFi Module, industrial high performance, with shield case, onboard antenna

Overview

WIFI232-A2 is a high performance UART WiFi module with shield case and onboard antenna. It is designed for occasions where large data flow is required and power consumption will not be a concern.

Features

  • Easy to use: just like a simple UART module (AT commands provided)
  • Start up time: 6s (most WiFi modules in the market require more than 6s to start up, even up to 30s)
  • Power consumption: 164mA-305mA@3.3V (suit for non-battery applications)
  • Shield case: protects the core circuit (usually no shielding for most other modules)
  • Ideal hotspot: supports connecting plenty devices, supports route/bridge modes (router AP solution)
  • TCPB function: supports 2x TCP, two network connections at the same time (rare feature in the market)

Functionality & Performance

  • Solution: Marvell WiFi (router solution, hardware AP), ARM
  • Wireless LAN protocols: IEEE 802.11 b/g/n
  • WIFI security algorithms: WEP/WPA-PSK/WPA2-PSK
  • Working modes: STA/AP/STA+AP (AP means WiFi hotspot, STA means terminal device)
    • AP mode: up to 32 devices
    • STA mode: server allows 32 connections
    • AP+STA mode: AP allows 32 clients with route function
  • Multi network protocols: TCP/UDP/ARP/ICMP/HTTP/DNS/DHCP
  • Supports DHCP, to allocate IP automatically
  • Supports AT+ instructions set and Web configuration
  • Supports Transparent/Agreement transmission modes, 4K TCP cache, totally 1M cache
  • Supports configuring UART framing delay and data volume
  • Up to 460800bps baudrate, supports hardware flow
  • Supports Ethernet data transmission, PWM output, GPIO control
  • Firmware is upgradable via web
  • Embedded PA, bi-transferring data on 57600 baudrate without packet loss, easily pass through three concrete walls
  • Communication distance: (between two modules under open and wide environment)
    • 280 metres with external 3DB antenna
    • 200 metres with onboard antenna
  • Supports factory reset: pull-down the Reload IO port for 3s, restore the module to its factory settings immediately
  • Supports route/bridge network architectures (thanks to the router solution)
  • Built-in watch dog and heartbeat mechanism to keep online

Software

  • Test software for WINDOWS, iOS, Android
  • Communication example source code for iOS, Android
