Wi-Fi module Inventek ISM43362-M3G-L44 (802.11 b/g/n)

The Inventek ISM43362-M3G-L44 module (M2) is implemented on top side of the STM32L4

Discovery kit for IoT node board. This module is an embedded (eS-WiFi) wireless Internet

Connectivity device. The Wi-Fi module hardware consists of an ARM® Cortex® -M3 STM32

host processor, an integrated antenna (or optional external antenna) and a Broadcom Wi-Fi

device. The module uses either a UART (UART3 of STM32L475VG) or an SPI (SPI3 of

STM32L475VG) interface. As default, an SPI interface is used, as the corresponding

firmware (for SPI capability) is downloaded on the Wi-Fi ISM43362-M3G-L44 module. The

Wi-Fi module requires no operating system and has a completely integrated TCP/IP stack

that only requires AT commands to establish connectivity for wireless product. The foot print

of this module is 14.5 mm x 30 mm.
