The ISM43903-R48-L54-E/U is an embedded 2.4 GHz Wi-Fi module. The Wi-Fi module hardware consists of a Cypress 43903 SOC with ARM Cortex-R4 clocked at 160 MHz (in 1× mode) or up to 320 MHz (in 2× mode), an integrated antenna or optional external antenna, 1 MB of SRAM and 640 KB ROM available for the applications processor, SPI or UART interface capability.

The Wi-Fi module requires no operating system and has an integrated TCP/IP stack that only requires development utilizing the Cypress WICED SDK. The module has a very small 14.5mm x 30mm surface mount footprint and has full FCC and CE module certification. (more…)
