1 System Descriptions
1.1 Applications
HWM-300 is a complete low power self-contained embedded wireless solution to address
the connectivity demand in M2M applications. It integrates micro-controller, Wi-Fi
BB/MAC/RF IC, RF front end, clocks, and on-board antenna into a small form factor module.
HWM-300 can be controlled by a host device through a serial interface; it can also serve as a
stand-alone Wi-Fi station or network controller. Thus, it can be used to enable wireless
connectivity to the simplest products with minimal engineering resources.
The HWM-300 provides standard IEEE802.11 b/g functions. The integrated CPU supports
software. It can be used for a variety of different applications, such as wireless sensor node,
serial to Wi-Fi transceiver, Wi-Fi network controller, Wi-Fi gateway/bridges plus internet
server.
When used in a system where the HWM-300 is controlled by a host CPU, the serial host
interface makes it very easy to integrate. When used in a system without a host CPU, the
integrated ARM9 CRUNOS can be used to run a variety of applications.
1.2 Module Summary
• 2.4GHz IEEE 802.11b/g radio technology
• Dimension: 33 mm × 48 mm × 1.2 mm
• On-board antenna
• Transmit power: +17 dBm @ 11b /11Mbps
• Max receive sensitivity: -92dBm
• CPU: ARM9 CRUNOS
• Diverse serial interface: UART
• Operating temperature range: -30ºC to 85ºC
• RoHS compliant
