The ISM4343-WBM-L151 is an embedded 2.4 GHz Wi-Fi and Bluetooth 4.2 combo module. The module hardware consists of the Cypress CYW4343 radio and ST Micro STM32F412 Cortex MCU. The Wi-Fi module requires no operating system and has an integrated TCP/IP stack that only requires a simple AT command or the Cypress WICED SDK set to establish connectivity for your wireless product.
The module has a very small 10 mm x 10 mm surface mount footprint and has FCC and CE module certification.
This product is targeted for low cost embedded wireless applications and enables a quick, easy and cost effective method adding Wi-Fi connectivity to your platforms. A summary of the key module features:
