B-L475E-IOT01A1 STM32L4 Discovery kit IoT node, low-power wireless, BLE, NFC, SubGHz, Wi-Fi

The B-L475E-IOT01A Discovery kit for IoT node allows users to develop applications with direct connection to cloud servers.

The Discovery kit enables a wide diversity of applications by exploiting low-power communication, multiway 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.
