ISM4343-M4G-L54 Wi-Fi / BT Combo Module

News Article Feature Image

The ISM4343-M4G-L54 is an embedded 2.4 GHz  Wi-Fi and Bluetooth 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 ISM4343-M4G-L54 is an embedded Serial WiFi (eS-WiFi), wireless internet connectivity module that operates in the 2.4GHz spectrum.  The eS-WiFi module’s hardware consists of an ARM Cortex M4 host processor, Cypress CYW4343 Single-Band (2.4GHz) 802.11 /b/g/n MAC/Baseband/Radio with Integrated Bluetooth 4.2.

Inventek’s IWIN, AT command set, allows you to quickly establish connectivity for your wireless product, minimizing development time, testing routines and certification. The low cost, small foot print (14.5 mm x 34 mm) and ease of design-in make it ideal for a range of embedded applications.
