New STM32 Discovery EVK Integrates Inventek Wi-Fi and Cloud Connectivity for IoT Development

Inventek Systems’ ISM43362-M3G-L44, 802.11 b/g/n Wi-Fi module and Inventek Systems’ IWIN proprietary connectivity SW, enables IoT applications for the ST Micro B-L475E-IOT01A Discovery kit. Users can now develop applications with direct connection to cloud servers. The Discovery kit enables a wide diversity of applications by exploiting low-power communication, multi-way sensing and ARM® Cortex® – M4 core-based STM32L4 Series features.

The support for Arduino Uno V3 and PMOD connectivity provides unlimited expansion capabilities with a large choice of specialized add-on boards.
