Inventek Systems ISM43362-M3G-L44 (802.11 b/g/n compliant Wi‑Fi
®
module)
The Inventek Systems ISM43362-M3G-L44 module (M2) is implemented on the top side of the B-L4S5I-IOT01A
Discovery kit for the IoT node This module is an embedded (eS-WiFi) wireless Internet Connectivity device. The
Wi‑Fi
®
hardware module 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 or an SPI interface
(UART3 or SPI3 of STM32L4S5VI). By 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 a wireless product. The footprint of this module is 14.5 mm x 30 mm.
