Description

Details

UART WiFi Module, low cost, small form factor, external antenna

Overview

WIFI-LPT100-B is a low cost UART WiFi module, nearly half size of the thumb, requires ultra low power consumption to keep working. It is an ideal choice for low flow communication situation.

Features

  • Easy to use: just like a simple UART module (AT commands provided)
  • Ultra low power: min [email protected] online power consumption in various low-power modes
  • Small form factor: size of a coin

Functionality & Performance

  • Solution: MTK single stream [email protected], ARM Cortex-M3
  • 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 3 devices
    • STA mode: server allows 5 connections
    • AP+STA mode: AP allows 3 clients
  • Multi network protocols: TCP/UDP/HTTP
  • Supports DHCP, to allocate IP automatically
  • Supports AT+ instructions set and Web configuration
  • Supports Transparent/Agreement transmission modes, with 1K cache
  • Supports configuring UART framing delay and data volume
  • Up to 460800bps baudrate
  • Supports Simple Config/Airkiss fast networking
  • Firmware is upgradable via web
  • Supports NTP datetime configuration
  • Supports UART heartbeat packet
  • Signal can pass through one wall
  • Communication distance: 200 metres with 3DB antenna (between two modules under open and wide environment)
  • Supports factory reset: pull-down the Reload IO port for 3s, restore the module to its factory settings immediately

Software

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