Overview

WIFI232-B2 is a high performance UART WiFi module with shield case and external 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
