STM32L4 Discovery Board for IoT node (B-L475E-IOT01A)
Hardware Description
The STM32L4 Discovery kit for the IoT node (B-L475E-IOT01A) allows users to
develop applications with direct connection to cloud servers. The STM32L4 Discovery
kit enables a wide diversity of applications by exploiting low-power multilink
communication (BLE, Sub- GHz), multiway sensing (detection, environmental
awareness) and ARM® Cortex®-M4 core-based STM32L4 Series features. Arduino™
Uno V3 and PMOD connectivity provide unlimited expansion capabilities with a large
choice of specialized add-on boards.
