Overview

The SG901-1071 CSR-Indigo module is a single chip based 802.11b/g/n WLAN radio for embedded, low-power and extremely small form factor mobile applications. The product conforms to the IEEE 802.11b, g, and n protocols operating in the 2.45GHz ISM frequency band supporting 802.11n modulations up to 72.2Mbps, all OFDM modulations and all mandatory 802.11b modulations.

The SG901-1049 Indigo is a fully integrated wireless radio including RF Synthesizer/VCO, high-speed data converters, digital baseband processor, onboard MAC and PHY processors, power management, Power Amplifier and LNA.

An on-board EEPROM stores calibration data for alignment-free integration.

Bluetooth integration features of the radio are made available.

An on-board crystal and filter simplify system integration. Just add one 1.8V regulator, 3.3V Power, Antenna, and host communications. For maximum flexibility, the SG901-1071 can optionally accept a wide range of external reference clock frequencies.

Host interface

Digital interfaces include both SDIO or SPI.

Software Support

This module is supported by a driver and Wi-Fi stack this is availble 100% source code for free. This code base is portable and the source code enables direct customer support.

Evaluation Kit Available

Part Number: SG923-0007

Overview

SG923-0007 Is an evaluation Kit used to simplify the rapid evaluation and software integration of the SG901-1071 Radio Module. The EVK allows for easy access to the SDIO interface via a standard SDIO hardware connector as well as a break out of each pin for debugging. The SDIO connector is designed to plug into processor development boards for rapid software testing.

The SG901-1080 Carrier board which hosts the SG901-1071 board also contains a debug connector which hosts the Blue Tooth coexistence control interface as well as a Debug SPI interface.

The evaluation kit can provide power to the module from a 3.3V SDIO socket or external input for instrumentation. A 2.4GHz antenna connection port as well as an optional external Bluetooth interface allow for complete system testing.

The Kit consists of a SG901-1071 soldered into a Carrier Board, Sagrad Part Number SG901-1080, Figure 1 and a SDIO/SPI Adapter Board, Sagrad Part number SG901-1042 depicted on Figure 2.

Most signals can also be used as general-purpose IO, and are available at standard 0.1” pitch headers for SPI applications and SDIO form factor for SDIO applications. An interface for external Bluetooth access is available in a 2mm pitch header.

Features

Easy to connect to SPI and SDIO header
Easy to use SDIO connector for common processor EVK.
