1. Section1:

1.1 Summary:

RMWIFI-M3 based on RMWIFI-M5 module provides a quick, easy and cost effective way to add Wi-Fi capabilities for RAE Systems products, such as AreaRAE2, MutlRAE2, and RAE-Hub etc. The module combined 802.11 MAC, security, PHY functions, FLASH SRAM, and external antenna connectors, provides a Wi-Fi radio for end customers. It also integrates TCP/IP stack and other related network stacks such as DHCP client, DHCP server and web server etc. It can be used to connect to Ethernet conveniently and transfer data to network server like ProRAE Guardian directly.

1.2 Key Features:

• 46 * 26 mm (Length * Width) with M3 40-PINs interface

• RCS protocol API for application interface

• DSSS modulation for 1and 2Mbps, CCK modulation for 5.5 and 11Mbps

• Compatible with IEEE 802.11 b

• UART interface, SPI interface, I2C interface, one ADC channel, several GPIOs

• Low power consumption

• RoHS compliant, certified lead- and halogen-free

2. Section2:

2.1 Overview:

RMWIFI-M3 operates in the unlicensed 2.4 radio bands IEEE 802.11b, which supports Direct Sequence Spread Spectrum (DSSS) 1 Mb/s and 2 Mb/s data rates, and Complementary Code Keyed (CCK) 5.5 Mb/s and 11 Mb/s data rates. RMWIFI-M3 is based on RMWIFI-M5 module, which contains GS1011 WIFI
