JUNIPER- WiFi Shield for Arduino Based on GainSpan Module

Introduction

The GS1011 module is a highly integrated ultra low power wireless single chip which contains an 802.11b radio, media access controller (MAC) and baseband processor, on-chip flash memory and SRAM, and an applications processor all on a single package.

Along with its embedded software stack it offers a highly scalable, reliable, manageable and secure wireless link to meet the growing demand of wireless sensor networks utilizing the broadly accepted IEEE 802.11b,g,n standards infrastructure.

Model:JUNIPER

Features

• Supports IEEE 802.11

• Seamlessly integrates with existing 802.11b/g infrastructure and utilizes the 802.11 security, manageability, ease-of-use, and quality of service

• 802.11i/WPA2 Authentication, AES Hardware encryption

• Optimized for battery powered application with very low power consumption for multiple years of battery life

• PCB antenna: Range 200-300M+ Outdoor (Typical Estimate)

• Two 32-bit ARM7 CPU @44MHz, 1 for applications (APP) : 1 dedicated to radio (WLAN)

• 2 UART , I2C, 2 SPI, 2 ADC, 3 PWM, and 32 GPIO

• Operates at 3.3V

Cautions

• As WiFi shares the Arduino hardware ports with FT232, when you download the programs, remove the WiFi module first.

• More details see: GS1011 data sheet，Schematic and samples.
