ISM43903-R48-L54 is an embedded wireless internet connectivity module that operates in the 2.4 GHz spectrum. The Wi-Fi module’s hardware consists of an ARM Cortex-based applications processor, a single stream IEEE 802.11n MAC/baseband/radio, a power amplifier (PA), and a receive low-noise amplifier (LNA). The module has two antenna options, an on board PCB etched antenna or an U.FL connector for external 2.4 GHz antenna.
The Wi-Fi module requires no operating system and has a completely integrated TCP/IP Stack. The module hardware can be used with Inventek’s AT Command set (IWIN) or with Cypress’ WICED SDK4.x or later.
• ARM Cortex-R4 clocked at 160 MHz (in 1× mode) or up to 320 MHz (in 2× mode).
• 1 MB of SRAM and 640 KB ROM available for the applications processor.
• 14.5mm x 30mm x 2.5 mm
• Input Voltage: 3.3 V
• Proven Interoperability … Connects with other vendor’s a/b/g/n Access Points in the Wireless LAN.
